Description

Technical Field

[0001] This utility model relates to the field of folding device technology, and in particular to a PE conductive film folding device. Background Technology

[0002] PE conductive film is a functional film made from polyethylene as a base material, with conductive components added through a specific process. This conductive film combines the excellent physical properties of polyethylene, such as good flexibility, chemical stability, and ease of processing and molding, with certain conductivity. It is mainly used in products such as computers, communication equipment, and medical instruments. A PE conductive film edge-folding device is a specialized device used to process the edges of PE (polyethylene) conductive film material. This device is typically used in the production process to ensure that the conductive film can better bond with other components or materials during application, and can improve the overall aesthetics and durability of the product.

[0003] A PE conductive film folding machine is disclosed in Chinese utility model patent with announcement number CN222309901U. The machine includes a machine base, a lifting and pressing frame is provided above the machine base, and an anti-wear rubber pad is fixed on the lower end face of the lifting and pressing frame. A pull-out mechanism is provided on the upper end face of the machine base. The pull-out mechanism includes a telescopic sliding sleeve and a forming boss. The telescopic sliding sleeve is fixed at the upper end face of the machine base, and the forming boss is inserted inside the telescopic sliding sleeve. A lifting mechanism is provided on one side of the forming boss. The lifting mechanism includes a lifting support plate, a drive motor and a height adjustment screw. The lifting support plate is fixed at the lower edge of one end face of the forming boss.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned equipment, when the PE conductive film is placed on the forming boss for edge folding, it is easily subject to external force factors and may shift, requiring the operator to place the PE conductive film in the accurate position again for edge folding, which reduces the edge folding efficiency of the PE conductive film. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a PE conductive film folding device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a PE conductive film folding device, comprising a machine base, an L-shaped connecting plate fixed to the top of the machine base and inverted, and a folding assembly disposed on the L-shaped connecting plate. The top of the machine base is provided with a lower mold for placing the PE conductive film, and the top of the machine base is provided with an installation groove for placing the lower mold. The top of the lower mold is provided with a lower mold slot. A ventilation slot communicating with the bottom of the installation groove is provided near the bottom of the machine base. Multiple air suction holes communicating with the ventilation slot are provided through the lower mold. An installation hole is provided through the bottom of the installation groove. An air extraction pipe communicating with the installation hole is provided at the bottom of the machine base. The air extraction pipe is connected to an external negative pressure device.

[0007] By adopting the above technical solution, when workers need to fold the PE conductive film, they only need to place the PE conductive film on top of the lower mold, ensuring that the bottom of the PE conductive film covers the air suction hole. Then, workers can use a negative pressure device to evacuate the air suction pipe, thereby drawing the air in the ventilation slot and multiple air suction holes to a slightly negative pressure state. This attracts the bottom of the PE conductive film to the position corresponding to the air suction hole (the slightly negative pressure state prevents the bottom of the PE conductive film from being sucked into the air suction hole), ensuring the stability of the PE conductive film during the folding process. This application changes the situation in traditional technology where the PE conductive film is easily shifted by external forces when placed on the lower mold, improving the efficiency and accuracy of workers folding the PE conductive film.

[0008] Furthermore, the lower mold groove is provided with a movable plate for supporting the PE conductive film and multiple sets of support components for supporting the movable plate. Each set of support components includes a mounting cylinder fixedly installed on the bottom wall of the lower mold groove, a sliding plate that slides with the inner wall of the mounting cylinder, a spring fixed between the bottom surface of the sliding plate and the bottom wall of the lower mold groove, and a support rod fixed to the top of the sliding plate. The upper end of the support rod passes through the top of the mounting cylinder and is clearance-fitted. The upper ends of multiple support rods are fixed together to the bottom of the movable plate.

[0009] By adopting the above technical solution, the movable plate effectively supports the PE conductive film above the lower mold groove. When the operator folds the PE conductive film placed on the lower mold using the folding assembly, the movable plate slides down along the mold groove due to the downward pressure of the folding assembly. The movable plate is compressed by the spring force, thereby achieving the folding of the PE conductive film. After the folding is completed, the movable plate returns to its original position under the spring force, so that the next folding operation can be carried out.

[0010] Furthermore, the top of the lower mold is provided with an indicator groove, which is located between the air intake hole and the outer wall of the lower mold. The indicator groove is provided with an indicator coating for indicating the installation position of the PE conductive film. The top of the movable plate and the top of the indicator coating are both flush with the top of the lower mold.

[0011] By adopting the above technical solution, the setting of the indicator coating makes it easier for workers to quickly place the PE conductive film in the designated position (the position of the indicator coating is set according to the folding requirements of the PE conductive film; when the edge of the PE conductive film is aligned with the indicator coating, it indicates that the position of the PE conductive film meets the requirements), which helps to improve the folding efficiency and accuracy of the PE conductive film.

[0012] Furthermore, the folding assembly includes an electric push rod fixed to the top of the horizontal section of the L-shaped connecting plate. The push rod of the electric push rod passes through the horizontal section of the L-shaped connecting plate and is slidably engaged. The folding assembly also includes a mounting plate fixed to the lower end of the push rod of the electric push rod and an upper mold fixed to the bottom of the mounting plate and engaged with the lower mold groove.

[0013] By adopting the above technical solution, when the staff needs to fold the PE conductive film through the upper mold, the staff only needs to adjust the electric push rod and make the push rod drive the mounting plate and the upper mold to move downward, so that the upper mold and the lower mold groove cooperate to fold the PE conductive film.

[0014] Furthermore, the width of the mounting groove is greater than the width of the ventilation groove, the length of the mounting groove is greater than the length of the ventilation groove, and an annular rubber sheet for sealing is provided between the inner wall of the mounting groove and the outer wall of the lower mold.

[0015] By adopting the above technical solution, the annular rubber sheet is made of rubber material. The lower mold and the mounting groove are matched and fully pressed against the annular rubber sheet, which ensures the sealing between the inner wall of the mounting groove and the outer wall of the lower mold, and prevents air leakage during the suction process of the negative pressure device, thereby ensuring the adsorption effect of PE conductive film.

[0016] Furthermore, the upper mold is provided with bolts for fixing the upper mold to the mounting plate, and the mounting plate is hinged with hooks on the side wall, which engage with the top edge of the upper mold.

[0017] By adopting the above technical solution, when workers need to install the upper mold onto the mounting plate, they can first temporarily fix the upper mold onto the mounting plate using hooks, and then fix the upper mold onto the mounting plate using bolts, which improves the efficiency of the workers' installation.

[0018] Furthermore, a cover plate is provided on the top of the movable plate, and the side wall of the cover plate is flush with the side wall of the lower mold.

[0019] By adopting the above technical solution, the cover plate can effectively prevent external impurities from entering the air intake hole and clogging it when the lower mold is not in use.

[0020] Furthermore, magnetic blocks that attract each other are embedded at positions corresponding to the bottom of the cover plate and the top of the lower mold.

[0021] By adopting the above technical solution, the magnetic block is set so that the cover plate fits more tightly against the upper surface of the lower mold, preventing the cover plate from being easily displaced or falling off due to external forces.

[0022] In summary, this utility model has the following beneficial effects: When workers need to fold the PE conductive film, they only need to place the PE conductive film on the top of the lower mold and make the bottom of the PE conductive film cover the air suction hole. Then, workers can use a negative pressure device to evacuate the air suction pipe, thereby drawing the air in the ventilation groove and multiple air suction holes to a slightly negative pressure state, thereby adsorbing the bottom of the PE conductive film at the position corresponding to the air suction hole (the slightly negative pressure state will not cause the bottom of the PE conductive film to be sucked into the air suction hole), ensuring the stability of the PE conductive film during the folding process.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-7 As shown in the figure, this application discloses a PE conductive film folding device, including a machine base 1, a lower mold 3, a folding assembly 2, and a support assembly 4. An inverted L-shaped connecting plate 12 is fixed to the top of the machine base 1, and the L-shaped connecting plate 12 is L-shaped. The lower mold 3 is disposed on the top of the machine base 1, and a mounting groove 13 for mounting the lower mold 3 is provided on the top of the machine base 1. A mounting hole 15 is provided through the bottom of the mounting groove 13. An exhaust pipe 16 communicating with the mounting hole 15 is fixed to the bottom of the machine base 1, and the exhaust pipe 16 is connected to an external negative pressure device (not shown in the figure). A ventilation groove 14 is provided inside the machine base 1 near its bottom, and the ventilation groove 14 communicates with the bottom of the mounting groove 13. The width of the mounting groove 13 is greater than the width of the ventilation groove 14, and the length of the mounting groove 13 is greater than the length of the ventilation groove 14. An annular rubber sheet 5 for sealing is provided between the inner wall of the mounting groove 13 and the outer wall of the lower mold 3.

[0033] The lower mold 3 has a lower mold groove 31 at its top. The shape of the lower mold groove 31 is set according to the PE conductive film to be folded (when processing different PE conductive films, the operator only needs to replace the lower mold 3 with a different shape and ensure that the lower mold 3 can be snapped into the mounting groove 13). In this embodiment, the lower mold groove 31 cooperates with the upper mold 23. The lower mold 3 has multiple air suction holes 32 through it, and the air suction holes 32 are connected to the ventilation groove 14.

[0034] The folding assembly 2 is mounted on the L-shaped connecting plate 12. The folding assembly 2 includes an electric push rod 21, a mounting plate 22, and an upper mold 23. The electric push rod 21 is fixed to the top of the horizontal section of the L-shaped connecting plate 12, and the push rod of the electric push rod 21 passes through the horizontal section of the L-shaped connecting plate 12 and slides in fit. The mounting plate 22 is fixed to the lower end of the push rod of the electric push rod 21, and the upper mold 23 is detachably mounted on the bottom of the mounting plate 22.

[0035] In this embodiment, a movable plate 33 is provided inside the lower mold groove 31, and the movable plate 33 is used to support the PE conductive film. Multiple sets of support components 4 are provided inside the lower mold groove 31, and these multiple sets of support components 4 cooperate to support the movable plate 33. The support component 4 includes a mounting cylinder 41, a sliding plate 42, a spring 43, and support rods 44. The mounting cylinder 41 is a cylindrical structure with a closed upper end, and its lower end is fixedly mounted on the inner bottom wall of the lower mold groove 31. The sliding plate 42 is disposed inside the mounting cylinder 41, and its outer wall slides in contact with the inner wall of the mounting cylinder 41. The spring 43 is fixed between the bottom surface of the sliding plate 42 and the inner bottom wall of the lower mold groove 31. The support rods 44 are fixed to the top of the sliding plate 42, and their upper ends penetrate the top of the mounting cylinder 41 with a clearance fit. The upper ends of multiple support rods 44 are jointly fixed to the bottom of the movable plate 33 (the top of the movable plate 33 is flush with the top of the lower mold 3).

[0036] When the operator needs to fold the PE conductive film, simply place the PE conductive film on top of the lower mold 3, ensuring the bottom of the PE conductive film covers the air suction hole 32. Then, the operator can use the negative pressure device to evacuate the air suction pipe 16, thereby drawing the air in the ventilation slot 14 and multiple air suction holes 32 to a slightly negative pressure state, thus adsorbing the bottom of the PE conductive film at the position corresponding to the air suction hole 32 (the slightly negative pressure state will not cause the bottom of the PE conductive film to be sucked into the air suction hole 32). Subsequently, when the operator folds the PE conductive film placed on the lower mold 3 using the folding assembly 2, the movable plate 33 slides down along the mold groove due to the downward pressure of the upper mold 23. The movable plate 33 is compressed due to the elastic force of the spring 43, thereby achieving the folding of the PE conductive film. After the folding is completed, the movable plate 33 returns to its original position under the elastic force of the spring 43, so that the next folding operation can be carried out.

[0037] In this embodiment, an indicator groove 34 is provided on the top of the lower mold 3, located between the air intake 32 and the outer wall of the lower mold 3. An indicator coating 35 is provided inside the indicator groove 34, which is used to indicate the installation position of the PE conductive film, and the top of the indicator coating 35 is flush with the top of the lower mold 3 and the top of the movable plate 33. The setting of the indicator coating 35 facilitates the worker to quickly place the PE conductive film in the designated position (the position of the indicator coating 35 is set according to the folding requirements of the PE conductive film; when the edge of the PE conductive film is aligned with the indicator coating 35, it indicates that the PE conductive film is placed in the required position), which helps to improve the folding efficiency and accuracy of the PE conductive film.

[0038] In this embodiment, bolts 6 are provided on the upper mold 23 to fix the upper mold 23 to the mounting plate 22. Hooks 7 are hinged to the side wall of the mounting plate 22 and engage with the top edge of the upper mold 23. When the operator needs to install the upper mold 23 onto the mounting plate 22, the operator can first temporarily fix the upper mold 23 to the mounting plate 22 using the hooks 7, and then fix the upper mold 23 to the mounting plate 22 using the bolts 6, which improves the efficiency of the operator's installation.

[0039] In this embodiment, a cover plate 8 is provided on the top of the movable plate 33, and the side wall of the cover plate 8 is flush with the side wall of the lower mold 3. The cover plate 8 can effectively prevent external impurities from entering the air suction hole 32 and clogging the air suction hole 32 when the lower mold 3 is not in use.

[0040] In this embodiment, magnetic blocks 9 are embedded at positions corresponding to the bottom of the cover plate 8 and the top of the lower mold 3, which are mutually attracted. The magnetic blocks 9 make the cover plate 8 fit more tightly against the upper surface of the lower mold 3, preventing the cover plate 8 from being displaced or falling off due to external forces.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
