Description

Technical Field

[0001] The present invention relates to the technical field of membrane switch embossing, and particularly to an automatic embossing device for manufacturing membrane switches. Background Art

[0002] A membrane switch is an operating system integrating button functions, indicating elements, and instrument panels. The membrane switch has the characteristics of a rigorous structure, beautiful appearance, good sealing, moisture-proof, and long service life, and is applied in the fields of electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances, etc.

[0003] The Chinese patent with the publication number CN221133702U proposes a membrane switch embossing machine, including a machine body, and further including a separation mechanism provided on the lower pressing frame for vibrating and separating the membrane switch from the lower pressing table. The separation mechanism includes sliding plates slidably connected to both sides of the lower pressing frame, and a vibrating plate is fixedly connected to the two sliding plates. A driving mechanism for driving the vibrating plate is provided on the upper pressing table. Through the setting of the separation mechanism, under the driving action of the driving mechanism, the vibrating plate is driven to reciprocally impact the side wall of the lower pressing frame, so that the membrane switch on the lower pressing table is stressed and vibrates. Under the action of the vibration force, the edge of the membrane switch warps up, so as to realize the separation of the edge of the membrane switch from the lower pressing table without directly contacting the membrane switch.

[0004] When the above device performs an embossing operation on a membrane switch, in order to avoid the inconvenience of staff taking, the edge of the membrane switch is made to warp up by means of impact vibration. Although the membrane switch in this way can indeed shake and warp due to the vibration force, there may be a situation where the vibration force is too small to cause the membrane switch to be successfully peeled off, and a situation where the vibration force is too large to cause the membrane switch to shake violently and fall off. Correspondingly, the stability during peeling cannot be guaranteed. Therefore, an automatic embossing device for manufacturing membrane switches is proposed here to solve the above problems.

[0052] During the actual operation process, first, power on this device. When working, the upper pressure plate 5 and the lower pressure plate 6 with different punch dies 75 and die cavities 76 can be flexibly loaded and unloaded according to the requirements of embossing. During specific installation, just place the upper pressure plate 5 and the lower pressure plate 6 into the interior of the second mounting seat 74 and the first mounting seat 72 respectively, and then rotate the second threaded rod 766 and the first threaded rod 765 respectively. After the second threaded rod 766 drives the second positioning plate 762 to insert into the interior of the upper pressure plate 5 and the first threaded rod 765 drives the first positioning plate 761 to insert into the interior of the lower pressure plate 6, the installation and fixation of the upper pressure plate 5 and the lower pressure plate 6 can be achieved. On the contrary, during disassembly, after controlling the first positioning plate 761 and the second positioning plate 762 to leave the interiors of the lower pressure plate 6 and the upper pressure plate 5 respectively, the two can be pulled out. While the upper pressure plate 5 and the lower pressure plate 6 are being loaded, unloaded and replaced, the supporting plate 792 also needs to be replaced accordingly. After selecting a supporting plate 792 that matches the die cavity 76, insert the insertion end of the supporting plate 792 into the interior of the connecting plate 791, and then rotate the threaded control rod 771. After the threaded control rod 771 drives the fixing plate 789 to move into the fixing groove on the inserted supporting plate 792, the fixed installation of the supporting plate 792 can be achieved, so as to quickly carry out loading and unloading to flexibly meet the requirements of embossing different switch films. After the selected supporting plate 792 is spliced with the corresponding die cavity 76, the grooved parts on the two can be well joined to form a die cavity for embossing and forming;

[0053] After the preparations for the current stage are completed, place the membrane switch to be processed on top of the female die 76. At this time, the clamping plate 795 and the supporting plate 792 are perpendicular to each other, which can prevent the clamping plate 795 from hindering the closing of the female die 76 and the male die 75. The air cylinder 73 pushes the mounting plate 4, the mounting plate 4 drives the second mounting seat 74 to move, and the second mounting seat 74 drives the upper pressure plate 5 to move. From the above connection relationship, it can be seen that at this time, the male die 75 and the female die 76 cooperate to complete the operation of pressing the convex on the membrane switch. After the pressing of the convex is completed, repeat the above similar steps to control the upper pressure plate 5 to rise and lift. Subsequently, after the second electric push rod 787 works, it pushes the movable plate 785, the movable plate 785 drives the rack 786 to move, the rack 786 drives the gear 783 to rotate during the movement, the gear 783 drives the square rod 794 to rotate, the square rod 794 drives the sleeve 796 to rotate, and after the sleeve 796 drives the clamping plate 795 to rotate to be parallel to the supporting plate 792, the first electric push rod 799 pushes the moving block 798, and the moving block 798 drives the push-pull rod 781 to swing after moving, prompting the push-pull rod 781 to push the rectangular plate 782, prompting the rectangular plate 782 to drive the sleeve 796 to move downward, then the sleeve 796 drives the clamping plate 795 to move downward until the membrane switch is clamped. Then, the third electric push rod 779 pushes the second cross plate 778 upward, and the second cross plate 778 can drive the two connecting plates 791 to move upward synchronously. From the above connection relationship, it can be seen that at this time, the supporting plate 792 and the clamping plate 795 move upward synchronously, and the membrane switch after the pressing of the convex can be lifted upward, so as to realize the function of blanking, and the blanking process is more stable and reliable, with strong safety;

[0054] After the membrane switch is lifted, the motor 775 works to drive the connected threaded adjusting rod 774 to rotate. This threaded adjusting rod 774 drives the external pulley 776 to rotate, and this pulley 776 drives another pulley 776 to rotate through the belt. Then, the two threaded adjusting rods 774 rotate synchronously at this time. The two threaded adjusting rods 774 drive the two sliders 78 to move synchronously, the sliders 78 drive the rectangular frame 79 to move, the threaded adjusting rod 774 drives the slider 78 to move, and the slider 78 drives the rectangular frame 79 to move. From the above connection relationship, it can be seen that in this way, the clamped membrane switch workpiece can be flexibly conveyed in any direction of the front and back sides, which is beneficial for conveying it to a suitable position for the staff to take.

[0055] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
