Description

Technical Field

[0001] This utility model relates to the field of membrane switch bonding technology, specifically a semi-automatic membrane switch bonding device. Background Technology

[0002] In the manufacturing process of membrane switches, the bonding of the membrane button to the flexible printed circuit board is one of the key processes, and its bonding quality directly affects the performance and lifespan of the membrane switch. Currently, the common method used in the industry for membrane switch bonding is as follows: workers first perform a preliminary bonding of the membrane button to the flexible printed circuit board, and then use a hand scraper to further press and bond the two together to ensure the stability of the bonding.

[0003] This traditional manual operation method has obvious drawbacks: on the one hand, the entire bonding process relies on manual hand-held scraper, which is labor-intensive, cumbersome, and results in low production efficiency; on the other hand, the consistency and accuracy of manual operation are difficult to guarantee, and the bonding quality is easily affected by factors such as uneven pressure and differences in operating techniques, which in turn causes fluctuations in product yield and affects bonding efficiency. Therefore, it is necessary to design a membrane switch semi-automatic bonding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a semi-automatic membrane switch bonding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a semi-automatic membrane switch bonding device, comprising a processing table, a bonding mechanism being provided on the top of the processing table, and a storage mechanism being provided on the right side of the bonding mechanism;

[0006] The bonding mechanism includes a load-bearing frame, which is fixedly connected to the right side of the processing table. A first servo motor is fixedly connected to the bottom front of the load-bearing frame, and a first rotating rod is fixedly connected to the rear of the first servo motor. A lower pressure roller is fixedly connected to the periphery of the first rotating rod. A hydraulic cylinder is fixedly connected to the top of the load-bearing frame, and a moving platform is fixedly connected to the bottom of the hydraulic cylinder. A top frame is fixedly connected to the bottom of the moving platform, and a telescopic column is fixedly connected inside the top frame. A bottom frame is fixedly connected to the bottom of the telescopic column, and a spring is sleeved around the telescopic column. A mounting frame is fixedly connected to the bottom of the bottom frame, and a fixed frame is fixedly connected to the front of the mounting frame. The fixed frame is slidably connected to the inside of the load-bearing frame. A second servo motor is fixedly connected to the front of the fixed frame, and a second rotating rod is fixedly connected to the rear of the second servo motor. An upper pressure roller is fixedly connected to the periphery of the second rotating rod.

[0007] Preferably, the first rotating rod is rotatably connected to the inside of the load-bearing frame, the moving platform is slidably connected to the inside of the load-bearing frame, the mounting frame is slidably connected to the inside of the load-bearing frame, and the outer periphery of the lower pressure roller is on the same plane as the top of the processing table, so as to facilitate the operation of the lower pressure roller by the first rotating rod.

[0008] Preferably, the top of the spring is fixedly connected to the top of the top frame, and the bottom of the spring is fixedly connected to the bottom of the bottom frame, so as to buffer the upper pressure roller under the action of the spring.

[0009] Preferably, the mounting bracket is fixedly connected to the front and rear sides with limiting shafts, which are slidably connected inside the load-bearing frame to ensure the stability of the mounting bracket when it moves.

[0010] Preferably, rubber pads are provided around the upper and lower pressure rollers, and the second rotating rod is rotatably connected inside the fixed frame and the mounting frame, so as to facilitate the operation of the upper pressure roller through the second rotating rod.

[0011] Preferably, the storage mechanism includes a connecting arm, which is fixedly connected to the front and rear sides of the processing table. A guide plate is fixedly connected to the inner side of the connecting arm, and a slide rail is fixedly connected to the bottom of the guide plate. A storage box is slidably connected inside the slide rail, and a fixed shaft is threadedly connected inside the storage box.

[0012] Preferably, the guide plate is located on the right side of the lower pressure roller, and the inner side of the guide plate is inclined. The fixed shaft passes through the inside of the slide rail, so that the laminated membrane switch can be stored in the storage box through the guide plate.

[0013] Compared with the prior art, the present invention provides a semi-automatic membrane switch bonding device, which has the following advantages:

[0014] 1. This semi-automatic membrane switch bonding device achieves semi-automatic bonding of membrane switches through a bonding mechanism. A first servo motor drives a first rotating rod and a lower pressure roller to rotate, while a second servo motor drives a second rotating rod and an upper pressure roller to rotate. The synchronous rotation of the upper and lower pressure rollers bonds the membrane switches. Furthermore, the upper and lower pressure rollers rotate in opposite directions, greatly improving bonding efficiency. A hydraulic cylinder drives the moving table, top frame, telescopic column, and bottom frame to move up and down, precisely controlling the downward pressure position of the upper pressure roller to ensure accurate bonding of the membrane switches. The springs around the telescopic column provide a cushioning effect. To prevent excessive pressure from damaging the membrane switch during the pressing process and to further ensure bonding quality, the limiting shafts on the front and rear sides of the mounting frame are slidably connected to the inside of the load-bearing frame, further enhancing the stability of the mounting frame during movement and ensuring that the upper pressure roller maintains a good working condition throughout the bonding process. The rubber pads on the outer periphery of the upper and lower pressure rollers prevent scratches on the surface of the membrane switch during bonding, improving the reliability of the device operation. After the operator performs preliminary bonding of the membrane button to the flexible printed circuit board, it can be directly placed between the upper and lower pressure rollers for further bonding, achieving semi-automatic operation.

[0015] 2. This semi-automatic membrane switch bonding device provides convenience for the storage and retrieval of membrane switches through its storage mechanism. The combination of connecting arm, guide plate, slide rail and storage box, with the guide plate located on the right side of the lower pressure roller and inclined on the inside, allows the bonded membrane switch to slide directly into the storage box, achieving seamless connection between production and storage. The fixed shaft with threaded connection inside the storage box runs through the slide rail, which can firmly fix the storage box and prevent it from sliding during the operation of the device. It also facilitates the disassembly and replacement of the storage box, making it convenient for centralized processing of the stored membrane switches. Attached Figure Description

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-5 This utility model provides a technical solution: a semi-automatic membrane switch bonding device, including a processing table 1, a bonding mechanism 2 on the top of the processing table 1, and a storage mechanism 3 on the right side of the bonding mechanism 2;

[0028] The bonding mechanism 2 includes a support frame 21, which is fixedly connected to the right side of the processing table 1. A first servo motor 22 is fixedly connected to the bottom front side of the support frame 21, and a first rotating rod 23 is fixedly connected to the rear side of the first servo motor 22. A lower pressure roller 24 is fixedly connected to the periphery of the first rotating rod 23. A hydraulic cylinder 25 is fixedly connected to the top of the support frame 21, and a moving table 26 is fixedly connected to the bottom of the hydraulic cylinder 25. A top frame 27 is fixedly connected to the bottom of the moving table 26, and a telescopic column 2 is fixedly connected inside the top frame 27. 8. A base frame 291 is fixedly connected to the bottom of the telescopic column 28. A spring 29 is sleeved around the telescopic column 28. A mounting bracket 292 is fixedly connected to the bottom of the base frame 291. A fixing bracket 296 is fixedly connected to the front side of the mounting bracket 292. The fixing bracket 296 is slidably connected to the inside of the load-bearing frame 21. A second servo motor 295 is fixedly connected to the front side of the fixing bracket 296. A second rotating rod 297 is fixedly connected to the rear side of the second servo motor 295. An upper pressure roller 293 is fixedly connected to the periphery of the second rotating rod 297.

[0029] The first rotating rod 23 is rotatably connected to the inside of the load-bearing frame 21, the moving table 26 is slidably connected to the inside of the load-bearing frame 21, the mounting bracket 292 is slidably connected to the inside of the load-bearing frame 21, and the outer periphery of the lower pressure roller 24 is on the same plane as the top of the processing table 1, so that the lower pressure roller 24 can be driven to work by the first rotating rod 23.

[0030] The top of the spring 29 is fixedly connected to the top of the top frame 27, and the bottom of the spring 29 is fixedly connected to the bottom of the bottom frame 291, so as to buffer the upper pressure roller 293 under the action of the spring 29.

[0031] The mounting bracket 292 is fixedly connected to the front and rear sides with limiting shafts 294. The limiting shafts 294 are slidably connected inside the load-bearing frame 21, so as to ensure the stability of the mounting bracket 292 when it moves.

[0032] Rubber pads are provided around the upper pressure roller 293 and the lower pressure roller 24. The second rotating rod 297 is rotatably connected to the inside of the fixed frame 296 and the mounting frame 292, so that the upper pressure roller 293 can be driven to work through the second rotating rod 297.

[0033] Example 2

[0034] Please see Figure 1-5 Furthermore, based on Embodiment 1, the storage mechanism 3 includes a connecting arm 31, which is fixedly connected to the front and rear sides of the processing table 1. A guide plate 32 is fixedly connected to the inner side of the connecting arm 31, and a slide rail 33 is fixedly connected to the bottom of the guide plate 32. A storage box 34 is slidably connected inside the slide rail 33, and a fixed shaft 35 is threadedly connected inside the storage box 34. The guide plate 32 is located to the right of the lower pressure roller 24, and the inner side of the guide plate 32 is inclined. The fixed shaft 35 passes through the inside of the slide rail 33, so that the laminated membrane switch can be stored in the storage box 34 through the guide plate 32.

[0035] In actual operation, when this device is used and the membrane switch needs to be bonded, the first servo motor 22 drives the first rotating rod 23 and the lower pressure roller 24 to rotate, and the second servo motor 295 drives the second rotating rod 297 and the upper pressure roller 293 to rotate. The synchronous rotation of the upper and lower pressure rollers 24 can bond the membrane switch. The upper pressure roller 293 rotates counterclockwise and the lower pressure roller 24 rotates clockwise. The two rollers rotate in opposite directions, which greatly improves the bonding efficiency.

[0036] During the bonding process, the hydraulic cylinder 25 drives the moving table 26, top frame 27, telescopic column 28, bottom frame 291, mounting frame 292 and upper pressure roller 293 to move, which can precisely control the pressing position of the upper pressure roller 293 and change the distance between the upper pressure roller 293 and the lower pressure roller 24 to ensure the accuracy of the membrane switch bonding position. The spring 29 on the periphery of the telescopic column 28 can play a buffering role to avoid excessive pressure during the pressing process and damage to the membrane switch, further ensuring the bonding quality. The limiting shafts 294 on the front and rear sides of the mounting frame 292 are slidably connected to the inside of the load-bearing frame 21, which further enhances the stability of the mounting frame 292 when moving and ensures that the upper pressure roller 293 always maintains a good working condition during the bonding process.

[0037] The rubber pads surrounding the upper pressure roller 293 and the lower pressure roller 24 prevent scratches on the surface of the membrane switch during the bonding process, thus improving the reliability of the device operation. After the gap between the upper pressure roller 293 and the lower pressure roller 24 is adjusted, the operator can initially bond the membrane switch to the flexible printed circuit board on the top of the processing table 1, and then place it directly between the upper pressure roller 293 and the lower pressure roller 24 for further bonding, realizing semi-automatic operation. After bonding, the membrane switch will enter the storage box 34 for storage under the action of the guide plate 32.

[0038] The guide plate 32 is located on the right side of the lower pressure roller 24 and is inclined on the inside, which makes it easy for the membrane switch after bonding to slide directly into the storage box 34, realizing a seamless connection between production and storage. The fixed shaft 35 with threaded connection inside the storage box 34 passes through the slide rail 33, which can firmly fix the storage box 34 and prevent it from sliding during the operation of the device. It also facilitates the disassembly and replacement of the storage box 34, and makes it easy to centrally process the stored membrane switches.

[0039] In this application, the first servo motor 22, the second servo motor 295, and the hydraulic cylinder 25 need to be connected to the same PLC controller to ensure the coordinated operation of the equipment and control the stroke distance of the hydraulic cylinder. The PLC control is existing technology, and the model is Siemens S7-1200. Those skilled in the art are well aware of the specific operation method of this controller, and it will not be described in detail in this application.
