Abstract
Description
Technical Field
[0001] This utility model relates to a surface mount pad device, specifically a surface mount pad device for FPC, and belongs to the field of FPC surface mount technology. Background Technology
[0002] With the rapid development of consumer electronics, automotive electronics, and smart wearables, the demand for thinner, smaller, and more flexible electronic products is becoming increasingly urgent. Flexible printed circuit boards (FPCs), with their lightweight, thinness, and bendability, have become the core carrier for connecting various electronic components. The soldering quality of FPC surface mount pads, as the key structure for achieving electrical connections between FPCs and other electronic components, directly determines the performance stability and lifespan of electronic products.
[0003] The utility model application with application number "202323610152.7" discloses a "device for FPC surface mount pads," which clamps the FPC by using a rotating component to fix the assembly and a rectangular telescopic plate via a threaded connection. However, this design reveals significant drawbacks in practical applications: First, the threaded connection requires multiple rotations, which takes time and significantly slows down production in mass production. Second, the fixing force relies entirely on the operator's experience; excessive force can easily cause wrinkles and breakage, while insufficient force can lead to FPC displacement during welding, resulting in mis-welding and other quality problems, thus causing poor fixing stability. Utility Model Content
[0004] The purpose of this invention is to provide an FPC pad mounting device to solve the above problems, which can quickly fix FPC pads and accurately control the fixing force to improve the fixing stability.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a device for FPC surface mount pads, comprising a device body, two support seats slidably connected to the device body, a movable rod slidably connected to the support seats, a fixed structure provided on the movable rod, the fixed structure including a support plate and a rotating shaft, the support plate fixedly connected to the movable rod, the rotating shaft rotatably connected to the support plate, an outer sliding sleeve sleeved on the outside of the rotating shaft, the outer sliding sleeve slidably connected to the movable rod, a guide shaft fixedly connected to the inner side of the outer sliding sleeve, a guide groove provided on the outer side of the rotating shaft, one end of the guide shaft extending into the interior of the guide groove, an inner sliding sleeve slidably connected to the inside of the outer sliding sleeve, a screw threadedly connected to the inside of the inner sliding sleeve, a component fixing assembly fixedly connected to one end of the screw, and a spring sleeved on the outer side of the screw.
[0006] Preferably, a protrusion is fixedly connected to the outer side of the screw, one end of the spring abuts against the protrusion, and the other end of the spring abuts against the outer sliding sleeve.
[0007] Preferably, the outer sliding sleeve has two second cut surfaces on its outer side, and the inner sliding sleeve has two first cut surfaces on its outer side.
[0008] Preferably, the guide groove has three sections, the first and third sections are horizontal, and the second section has a spiral structure.
[0009] Preferably, a handle is fixedly connected to the rotating shaft, and the handle is perpendicular to the rotating shaft.
[0010] Preferably, the support plate has an L-shaped cross-section, and the protrusion has a hexagonal cross-section.
[0011] Preferably, the device body is provided with two sliding grooves, the bottom end of the support base is slidably engaged with the sliding grooves, one end of the sliding groove is provided with an opening, and one side of the sliding groove is provided with multiple through holes, one of the through holes is provided with a second bolt, and one end of the second bolt is threadedly connected to the support base.
[0012] Preferably, the support base is threaded with a first bolt, and the movable rod is provided with multiple sockets, with one end of the first bolt engaging with one of the sockets.
[0013] Preferably, a shelf is rotatably connected to one side of the device body, and two support rods are rotatably connected to one side of the device body. One end of the two support rods abuts against the bottom side of the shelf. Two abutting blocks are fixedly connected to the bottom side of the shelf. One end of the support rod abuts against the adjacent abutting block. A third bolt is threaded onto the support rod.
[0014] The beneficial effects of this utility model are as follows: When it is necessary to fix the FPC, the rotating shaft can be rotated. During the rotation, the guide shaft will move inside the guide groove. When the guide shaft moves in the first horizontal position of the guide groove, the outer sliding sleeve will not move. When the guide shaft moves inside the second section of the guide groove, which has a spiral structure, the outer sliding sleeve will slide on the movable rod. The component fixing assembly will move together with the outer sliding sleeve. During the movement, the bottom end of the component fixing assembly will abut against the FPC. Then, as the outer sliding sleeve continues to move, the inner sliding sleeve will slide inside the outer sliding sleeve, and the spring will contract. The rotating shaft can be stopped after rotating 180 degrees. When the guide shaft moves to the third horizontal position of the guide groove, the spring will not extend after the shaft is released, thus completing the fixation of the FPC. Since only 180 degrees of rotation of the shaft is required for fixation, the fixation time can be shortened. At the same time, the spring can be compressed a specified distance after each fixation, thus providing constant pressure to the FPC each time. This avoids damage to the FPC due to excessive pressure and insecure fixation due to insufficient pressure, thereby improving the stability of fixation. When the spring performance deteriorates, the screw can be unscrewed from the inner sleeve, and then the spring can be removed and replaced, which facilitates the inspection and maintenance of the spring.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-7 As shown, an FPC pad mounting device includes a device body 1. Two support seats 2 are slidably connected to the device body 1. A movable rod 3 is slidably connected to the support seats 2. A fixing structure 4 is provided on the movable rod 3. The fixing structure 4 includes a support plate 401 and a rotating shaft 402. The support plate 401 is fixedly connected to the movable rod 3. The rotating shaft 402 is rotatably connected to the support plate 401. An outer sliding sleeve 406 is sleeved on the outside of the rotating shaft 402. The outer sliding sleeve 406 is slidably connected to the movable rod 3. A guide shaft 405 is fixedly connected to the inside of the outer sliding sleeve 406. A guide groove 404 is provided on the outside of the rotating shaft 402. One end of the guide shaft 405 extends into the inside of the guide groove 404. An inner sliding sleeve 407 is slidably connected inside the outer sliding sleeve 406. A screw 408 is threadedly connected inside the inner sliding sleeve 407. A component fixing assembly 409 is fixedly connected to one end of the screw 408. A spring 411 is sleeved on the outside of the screw 408.
[0019] As a technical optimization of this utility model, a protrusion 410 is fixedly connected to the outer side of the screw 408, so that a wrench can be inserted into the protrusion 410, thereby facilitating the unscrewing of the screw 408 to replace the spring 411. One end of the spring 411 abuts against the protrusion 410, and the other end of the spring 411 abuts against the outer sliding sleeve 406.
[0020] As a technical optimization of this utility model, the outer sliding sleeve 406 has two second cut surfaces 413 on its outer side, which can prevent rotation between the outer sliding sleeve 406 and the movable rod 3. The inner sliding sleeve 407 has two first cut surfaces 412 on its outer side, which can prevent rotation between the inner sliding sleeve 407 and the outer sliding sleeve 406.
[0021] As a technical optimization of this utility model, the guide groove 404 is provided with three sections. The first and third sections are horizontally arranged, and the second section has a spiral structure. Therefore, when the guide shaft 405 is located inside the first and third sections of the guide groove 404, it can limit the outer sliding sleeve 406 and prevent the outer sliding sleeve 406 from sliding on the movable rod 3. Therefore, when the guide shaft 405 moves inside the second section of the guide groove 404, the outer sliding sleeve 406 will slide on the movable rod 3.
[0022] As a technical optimization of this utility model, a handle 403 is fixedly connected to the rotating shaft 402. The handle 403 is perpendicular to the rotating shaft 402, so the rotating shaft 402 can be rotated by holding the handle 403.
[0023] As a technical optimization of this utility model, the support plate 401 has an L-shaped cross-section, so the rotating shaft 402 can be supported by the support plate 401, and the protrusion 410 has a hexagonal cross-section.
[0024] As a technical optimization of this utility model, the device body 1 is provided with two sliding grooves 9, and the bottom end of the support seat 2 is slidably engaged with the sliding groove 9. One end of the sliding groove 9 is provided with an opening 10, so the support seat 2 can be inserted into the interior of the sliding groove 9 from the opening 10. One side of the sliding groove 9 is provided with multiple through holes 8, and a second bolt 7 is inserted through the interior of one of the through holes 8. One end of the second bolt 7 is threadedly connected to the support seat 2. Therefore, the position of the support seat 2 can be adjusted by inserting the second bolt 7 into the interior of different through holes 8 and then threading it with the support seat 2.
[0025] As a technical optimization of this utility model, the support base 2 is threaded with a first bolt 5, and the movable rod 3 is provided with multiple sockets 6. One end of the first bolt 5 is engaged with one of the sockets 6, so the position of the movable rod 3 can be adjusted by inserting the first bolt 5 into different sockets 6.
[0026] As a technical optimization of this utility model, a shelf 11 is rotatably connected to one side of the device body 1, and two support rods 13 are rotatably connected to one side of the device body 1. One end of the two support rods 13 abuts against the bottom side of the shelf 11. Two blocks 12 are fixedly connected to the bottom side of the shelf 11. One end of the support rod 13 abuts against the adjacent block 12. A third bolt 14 is threaded onto the support rod 13. Therefore, it is possible to place items. At the same time, when the device body 1 is not needed, the shelf 11 can be stored, thereby reducing space occupation and improving space utilization efficiency.
[0027] In use, when the FPC needs to be fixed, the rotating shaft 402 can be rotated by holding the handle 403. During the rotation of the rotating shaft 402, the guide shaft 405 will move inside the guide groove 404. When the guide shaft 405 moves in the first horizontal position of the guide groove 404, the outer sliding sleeve 406 will not move. When the guide shaft 405 moves in the second spiral structure of the guide groove 404, the outer sliding sleeve 406 will slide on the movable rod 3, and the component fixing assembly 409 will move together with the outer sliding sleeve 406. During the movement, the bottom end of the component fixing assembly 409 will abut against the FPC. Then, as the outer sliding sleeve 406 continues to move, the inner sliding sleeve 407 will slide inside the outer sliding sleeve 406, and the spring 411 will contract. When the rotating shaft 402 rotates 180 degrees, it can be stopped. At this time, the guide shaft 405 moves to the third horizontal position of the guide groove 404. Therefore, the spring 411 will not extend after the handle 403 is released, and the FPC is fixed. Since only the rotating shaft 402 needs to be rotated 180 degrees for fixing, the fixing time can be shortened. At the same time, after each fixing, the spring 411 can be compressed a specified distance, thus providing constant pressure to the FPC each time. This avoids damage to the FPC due to excessive pressure and insecure fixing due to insufficient pressure, thereby improving the stability of the fixing. When the performance of the spring 411 deteriorates, the screw 408 can be pulled out from the inner sleeve 4 by locking the wrench on the protrusion 410. Twist 07 up and down, and then the spring 411 can be removed and replaced, facilitating the inspection and maintenance of the spring 411. When the position of the support 2 needs to be changed, the second bolt 7 can be turned. After the end of the second bolt 7 disengages from the inside of the support 2, the support 2 can be pushed to slide inside the slide groove 9. After the position adjustment is completed, the second bolt 7 can be taken out from the inside of one of the through holes 8, and then inserted into the inside of the other through hole 8. Finally, it can be turned back onto the support 2, thereby fixing the position of the support 2 after adjustment. When the position of the movable rod 3 needs to be adjusted, the first bolt 5 can be rotated. When the end of the first bolt 5 and one of the sockets 6 are not engaged, the movable rod 3 can be pushed to slide on the support 2. When the position is adjusted... Then, the first bolt 5 is twisted again to engage its end with another socket 6, thereby fixing the movable rod 3 after adjustment. By adjusting the positions of the support base 2 and the movable rod 3, the position of the component fixing assembly 409 can be adjusted, thus facilitating the fixing of FPCs of different sizes. Items can be placed on the shelf 11. The shelf 11 is supported by the two support rods 13 and the two abutments 12. During the support of the shelf 11, the third bolt 14 can be twisted to engage its end with the abutment 12, thus preventing the shelf 11 from rotating after impact and effectively improving its stability. When the equipment body 1 is not in use, the shelf 11 can be rotated upwards.Once the stop block 12 ceases to block the support rod 13, the support rod 13 can rotate toward the equipment body 1, and then the shelf 11 can rotate toward the equipment body 1. Therefore, when the equipment body 1 is not in use, the shelf 11 can be stored on one side of the equipment body 1, thereby reducing space occupation and improving space utilization efficiency.
