Description

Technical Field

[0001] This utility model relates to the technical field of membrane keypad production equipment, and in particular to a device for bulging of membrane keypads on household appliance panels. Background Technology

[0002] Bulging machines, also known as hydraulic bulging machines or hot-press bulging machines, are ubiquitous in our daily production. The buttons and switches on various instruments and electronic products are all made using bulging machines to create this bulging effect.

[0003] Different panel models require pressure molding of buttons at different positions on the diaphragm, necessitating the use of different templates for production. Production is achieved by installing these templates onto pressure plates. Existing template installation methods rely on bolts and similar structures, which are cumbersome to install and disassemble. Furthermore, the limited operating space between the upper and lower pressure plates makes operation inconvenient and increases the risk of collisions and injuries. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a device for bulging of key positions on the panel of a household appliance, so as to solve the problem of inconvenient installation of bulging templates.

[0005] Based on the above objectives, this utility model provides a device for bulging key positions on a household appliance panel, including a frame, an upper pressure plate and a lower pressure plate mounted on the frame, a drive cylinder mounted on the upper end of the frame, the output end of the drive cylinder being connected to the upper pressure plate, an upper template and a lower template respectively provided on the upper and lower pressure plates, an installation mechanism provided between the upper pressure plate and the upper template, and between the lower pressure plate and the lower template, the installation mechanism being used for quick installation of the upper template and the lower template, and a pressing mechanism provided on both sides of the lower pressure plate, the pressing mechanism being used to position and flatten the conveyed material.

[0006] A further improvement is that the installation mechanism includes installation grooves formed on the upper and lower pressure plates, with the upper and lower templates respectively installed in the corresponding installation grooves. A through groove is provided on one side of the installation groove, and a pin is slidably installed in the through groove. A slot is provided on one side of the upper and lower templates, and the pin is adapted to the slot.

[0007] A further improvement is that a limiting block is installed on the upper end of the other side of the mounting groove, and a snap-fit ​​block is correspondingly connected to the lower end of the other side of the upper and lower templates, with the limiting block and the snap-fit ​​block being compatible.

[0008] A further improvement is that the end of the pin extends to one side of the upper and lower pressure plates, and a return spring is connected between the end of the pin and the side of the upper and lower pressure plates.

[0009] A further improvement is that the pressing mechanism includes two sets of pressing plates. The surface of the lower pressing plate is provided with a sliding groove. The lower end of the pressing plate is slidably disposed in the sliding groove. A bidirectional screw is rotatably installed in the sliding groove. The two sets of pressing plates are respectively threaded to both ends of the bidirectional screw.

[0010] A further improvement is that guide grooves are provided on the upper pressure plate and the upper template corresponding to the pressure plate.

[0011] The beneficial effects of this utility model are as follows: by setting an installation groove for installing the upper and lower templates, one end of the upper and lower templates is fixed by a limiting block and a snap-fit ​​block, and the other end is fixed by a pin and a slot; when installing and disassembling the upper and lower templates, it is controlled only by inserting and pulling out the pin, which greatly improves the efficiency of installation and disassembly and improves the convenience of operation.

[0012] By setting up pressure plates, the film is limited on both sides of the lower template to prevent deviation during transportation. The film is also flattened by the pressure blocks during transportation, ensuring the flatness of the film on the lower template and preventing wrinkles. This greatly improves the quality of film pressure bulging. Attached Figure Description

[0018] like Figure 1 As shown, this embodiment provides a device for bulging the key positions of a household appliance panel with film coating. It includes a frame 1, an upper pressure plate 2 and a lower pressure plate 3 mounted on the frame 1, a drive cylinder 4 mounted on the upper end of the frame 1, and the output end of the drive cylinder 4 connected to the upper pressure plate 2. The upper pressure plate 2 and the lower pressure plate 3 are respectively provided with an upper template 5 and a lower template 6, and the upper template 5 and the lower template 6 are respectively provided with forming grooves and forming protrusions. The drive cylinder 4 drives the upper pressure plate 2 to move downward, so that the upper template 5 and the lower template 6 close, and pressurize and bulge the film in the middle.

[0019] like Figure 2 , Figure 3As shown, installation mechanisms are provided between the upper pressure plate 2 and the upper template 5, and between the lower pressure plate 3 and the lower template 6. These mechanisms are used for the quick installation of the upper template 5 and the lower template 6. Each installation mechanism includes an installation groove 7 formed on the upper pressure plate 2 and the lower pressure plate 3. The upper template 5 and the lower template 6 are respectively installed in their corresponding installation grooves 7. A retrieval groove is provided on the side of the installation groove 7 to facilitate the removal of the upper template 5 and the lower template 6 from the installation groove 7. A limiting block 11 is installed at the upper end of one side of the installation groove 7. A corresponding snap-fit ​​block 12 is connected to the lower end of one side of the upper template 5 and the lower template 6. The limiting block 11 and the snap-fit ​​block 12 are compatible, forming a slot between the limiting block 11 and the bottom of the installation groove 7. After the lower template 6 is installed in the installation groove 7, the snap-fit ​​block 12 snaps into the slot. The limiting block 11 limits the snap-fit ​​block 12, thus fixing one end of the lower template 6. On the other side of the mounting slot 7, a through slot 8 is provided, in which a pin 9 is slidably installed. On the other side of the upper template 5 and the lower template 6, a slot 10 is provided, and the pin 9 is adapted to the slot 10. The end of the pin 9 extends to one side of the upper pressure plate 2 and the lower pressure plate 3. A return spring 13 is connected between the end of the pin 9 and the side of the upper pressure plate 2 and the lower pressure plate 3. Magnetic blocks are provided correspondingly on the end of the pin 9 and the side of the upper pressure plate 2 and the lower pressure plate 3. When the pin 9 locks the upper template 5 and the lower template 6, the magnetic blocks attract each other, further ensuring the stability of the pin 9, thereby ensuring the stability of locking the upper template 5 and the lower template 6. After the lower template 6 is engaged in the mounting groove 7, release the pin 9 so that the pin 9 extends into the mounting groove 7 and is inserted into the slot 10 by the action of the return spring 13, thus fixing one end of the lower template 6. The two ends of the lower template 6 are respectively fixed by the limit block 11 and the pin 9. When disassembling, pull the pin 9 to pull it out of the slot 10, release the limit on one end of the lower template 6, and then directly remove the lower template 6 from the mounting groove 7.

[0020] The lower pressure plate 3 is equipped with a pressing mechanism on both sides, which positions and flattens the conveyed material. The pressing mechanism includes two sets of pressing plates 14. The surface of the lower pressure plate 3 is provided with a sliding groove 15. The lower end of the pressing plate 14 is slidably disposed in the sliding groove 15. A bidirectional screw 16 is rotatably installed in the sliding groove 15. The two sets of pressing plates 14 are respectively threaded to both ends of the bidirectional screw 16. One end of the bidirectional screw 16 passes through the sliding groove 15 and is fixedly connected to a handle. By driving the bidirectional screw 16 to rotate through the handle, the pressing plate 14 slides in the sliding groove 15 toward the lower template 6 in the middle. The pressing plate 14 is 7-shaped.

[0021] like Figure 4 As shown, the upper pressure plate 2 and the upper template 5 have corresponding pressure plates 14 with guide grooves 19. As the upper pressure plate 2 and the lower pressure plate 3 gradually approach each other, the pressure plates 14 extend into the guide grooves 19 to play a guiding role and ensure the alignment between the upper pressure plate 2 and the lower pressure plate 3.

[0022] During processing, the film is released from the take-up roller on one side of the frame 1 and conveyed through the frame 1 to the other side. The film is adhered to the lower template 6. The bidirectional screw 16 is rotated to drive the pressure plate 14 to limit the film on the lower template 6. When the film passes through the lower template 6, the pressure plate 14 flattens the film. The drive cylinder 4 drives the upper pressure plate 2 and the upper template 5 to move down. The pressure plate 14, in conjunction with the guide groove 19, guides the upper pressure plate 2 and the lower pressure plate 3 to ensure the accuracy of pressure forming. The upper template 5 and the lower template 6 close to pressurize and bulge the bonding mold. Through the continuous conveying of the film, the drive cylinder 4 drives the upper template 5 to move up and down back and forth, realizing continuous bulging operation of the film and improving production efficiency. When it is necessary to replace the upper template 5 and the lower template 6, simply pull out the pin 9, remove the upper template 5 and the lower template 6 from the mounting slot 7, then snap the new upper template 5 and the lower template 6 into the mounting slot 7, and loosen the pin 9 to insert it into the slot 10, thereby completing the installation of the upper template 5 and the lower template 6, which greatly improves the convenience of operation.
