Description

Technical Field

[0001] This utility model relates to the field of circuit board fixture technology, specifically to a flexible contact anti-scratch auxiliary circuit board fixture. Background Technology

[0002] In the field of electronics manufacturing, circuit boards are a key component of various electronic devices. The precision and quality of their production and processing directly affect the performance and reliability of electronic products. With the rapid development of electronic technology, electronic devices are constantly moving towards miniaturization and high performance, which places more stringent requirements on the dimensional accuracy, surface quality, and processing efficiency of circuit boards.

[0003] In the electronics manufacturing industry, the circuit board processing stage is crucial, and its positioning and fixing methods directly affect processing quality and efficiency. Traditional fixtures use a relatively rigid method to limit the circuit board, usually using fixed claws or blocks to directly squeeze the edge of the circuit board. This rigid contact is prone to scratches and wear on the surface of the circuit board due to improper control of the clamping force during the limiting process. Especially for some circuit boards with special coatings or fine lines, the damage will seriously affect their electrical performance and service life. Therefore, those skilled in the art provide a flexible contact anti-scratch auxiliary circuit board fixture to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this utility model is to provide a flexible contact anti-scratch auxiliary circuit board fixture to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a flexible contact anti-scratch auxiliary circuit board fixture, including a worktable, four connecting frames are symmetrically fixedly connected to the outer side wall of the worktable, and a placement plate is fixedly connected to one side of the four connecting frames opposite to each other. The upper top of the worktable is provided with limiting mechanisms on both sides of the placement plate to limit the circuit board, and the upper top of the worktable is provided with a lifting mechanism for extruding the circuit board below the placement plate.

[0006] Preferably, each set of limiting mechanisms includes two hydraulic push rods symmetrically fixedly connected to the top of the workbench on one side of the placement plate. The telescopic ends of the two hydraulic push rods are jointly fixedly connected to a first fixed plate. The top of the first fixed plate is symmetrically fixedly connected to two auxiliary brackets. The interior of each of the two auxiliary brackets is rotatably fitted with a movable roller.

[0007] Preferably, the top of the placement plate is symmetrically fixedly connected to two side plates, and a rotating blade is rotatably sleeved on the opposite side of the two side plates. Two movable rollers are rotatably abutted against the bottom of the rotating blade. Three movable brackets are rotatably sleeved at the end of the rotating blade. An arc-shaped connecting strip is fixedly connected to the bottom of the three movable brackets. A rubber plate that limits the edge of the circuit board is fixedly connected to the bottom of the arc-shaped connecting strip.

[0008] Preferably, two first connecting frames are symmetrically fixedly connected to the lower bottom end of the rotating blade, and two second connecting frames are symmetrically fixedly connected to the outer side wall of the placement plate. Each first connecting frame and the second connecting frame are internally movably sleeved with a tension spring. A second fixing plate is fixedly connected to the outer side wall of the placement plate between the two second connecting frames. A second limiting rod for preventing the rotating blade from moving excessively downward is fixedly connected to the upper top end of the second fixing plate.

[0009] Preferably, the lifting mechanism includes fixed brackets symmetrically fixedly connected to the top of the worktable, and two bidirectional electric push rods are fixedly connected inside the two fixed brackets. Each of the two telescopic ends of the bidirectional electric push rods is fixedly connected to a first inclined block, and the bottom ends of the two first inclined blocks are slidably sleeved with the top of the worktable.

[0010] Preferably, a connecting plate is slidably sleeved at the middle of the lower bottom end of the placement plate, the connecting plate is slidably connected to the worktable, four lifting rods are symmetrically fixedly connected to the upper top of the connecting plate, and two second inclined blocks are symmetrically fixedly connected to the lower bottom end of the connecting plate.

[0011] Preferably, the bottom ends of each of the first and second inclined blocks slide against each other, and four extrusion holes are opened through the interior of the placement plate. Each of the lifting rods is located inside the extrusion hole. Four first limiting rods are symmetrically fixedly connected to the top of the worktable. The first limiting rods are used to position the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes a symmetrically arranged limiting mechanism. The circuit board to be processed is placed on the top of the placement plate. Then, the extension end of the hydraulic push rod drives the first fixed plate and the movable roller to move upward. The movable roller then squeezes the rotating blade. Since the rotating blade is limited by the side plate, the end of the rotating blade will move downward under the squeezing of the movable roller. The rubber plate and the arc-shaped connecting strip can adjust the angle between the rubber plate and the rotating blade through the arc-shaped movement of the movable bracket and the rotating blade. The rubber plate and the placement plate will be parallel to each other, thus contacting the circuit board above the placement plate. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution: a flexible contact anti-scratch auxiliary circuit board fixture, including a workbench 1, four connecting frames 2 are symmetrically fixedly connected to the outer side wall of the workbench 1, and a placement plate 3 is fixedly connected to one side of the four connecting frames 2 on opposite sides. The upper top of the workbench 1 is provided with limiting mechanisms 5 on both sides of the placement plate 3 to limit the circuit board, and the upper top of the workbench 1 is provided with a lifting mechanism 4 for extruding the circuit board below the placement plate 3.

[0023] It should be noted that four connecting brackets 2 are symmetrically fixed to the outer wall of the workbench 1. The four connecting brackets 2 together provide stable support for the placement plate 3, creating a reliable foundation for the circuit board and ensuring the stability of the circuit board during operation. The limiting mechanism 5 equipped on both sides of the placement plate 3 can accurately limit the circuit board, preventing displacement during processing, greatly improving the accuracy of circuit board processing, and effectively reducing the defect rate caused by circuit board misalignment. At the same time, the lifting mechanism 4 set on the workbench 1 below the placement plate 3 can smoothly and gently push out the circuit board when it needs to be removed, achieving flexible contact and avoiding scratches that may be caused by traditional methods. This greatly protects the surface quality of the circuit board and extends its service life.

[0024] As one implementation method in this embodiment, please refer to Figures 2-5 As shown, each set of limiting mechanisms 5 includes two hydraulic push rods 51 symmetrically fixedly connected to the top of the workbench 1 on one side of the placement plate 3. The telescopic ends of the two hydraulic push rods 51 are fixedly connected to a first fixed plate 511. The top of the first fixed plate 511 is symmetrically fixedly connected to two auxiliary brackets 512. The interior of each of the two auxiliary brackets 512 is rotatably fitted with a movable roller 513.

[0025] It should be noted that the first fixed plate 511 connected to the telescopic end of the hydraulic push rod 51 provides a stable mounting base for the movable roller 513, and can drive the height position of the first fixed plate 511 and the movable roller 513 to be adjusted, thereby cooperating with the other structures in the limiting mechanism 5.

[0026] As one implementation method in this embodiment, please refer to Figures 2-5 As shown, two side plates 53 are symmetrically fixedly connected to the top of the placement plate 3. A rotating blade 52 is rotatably sleeved on the opposite side of the two side plates 53. Two movable rollers 513 are movably abutted against the bottom of the rotating blade 52. Three movable brackets 54 are rotatably sleeved at the end of the rotating blade 52. An arc-shaped connecting strip 55 is fixedly connected to the bottom of the three movable brackets 54. A rubber plate 56 that limits the edge of the circuit board is fixedly connected to the bottom of the arc-shaped connecting strip 55. Two first connecting frames 57 are symmetrically fixedly connected to the bottom of the rotating blade 52. Two second connecting frames 571 are symmetrically fixedly connected to the outer wall of the placement plate 3. A tension spring 572 is movably sleeved inside each first connecting frame 57 and the second connecting frame 571. A second fixing plate 58 is fixedly connected between the two second connecting frames 571 on the outer wall of the placement plate 3. A second limiting rod 59 for preventing the rotating blade 52 from moving excessively downward is fixedly connected to the top of the second fixing plate 58.

[0027] It should be noted that the two symmetrical side plates 53 on the placement plate 3 are rotatably sleeved with the rotating blade 52. The movable roller 513 abuts against the bottom of the rotating blade 52. When the hydraulic push rod 51 pushes the movable roller 513 to move, it can drive the rotating blade 52 to rotate flexibly and achieve flexible positioning. The end of the rotating blade 52 is connected to the arc-shaped connecting strip 55 through three movable brackets 54. The rubber plate 56 at the lower end of the arc-shaped connecting strip 55 is positioned against the edge of the circuit board. The rubber plate 56 is soft and has a certain degree of elasticity, which can effectively fix the circuit board and prevent it from shaking, and can also... To prevent scratches on the edges of the circuit board and protect its quality, the first connecting bracket 57 and the second connecting bracket 571 are movably connected to a tension spring 572. The tension spring 572 provides elastic restoring force, allowing the rotating blade 52 to remain stable when not subjected to external force. During operation, the tension spring 572 can buffer external impacts and reduce damage to the circuit board. The second limiting rod 59 on the second fixing plate 58 can prevent the rotating blade 52 from moving downwards excessively, avoiding squeezing the circuit board due to excessive downward movement of the rotating blade 52, and further ensuring the safety of the circuit board.

[0028] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the lifting mechanism 4 includes fixed brackets 41 symmetrically fixedly connected to the top of the workbench 1. Two bidirectional electric push rods 42 are fixedly connected inside the two fixed brackets 41. Two telescopic ends of the bidirectional electric push rods 42 are fixedly connected to first inclined blocks 43. The bottom ends of the two first inclined blocks 43 are slidably sleeved with the top of the workbench 1. A connecting plate 45 is slidably sleeved at the middle of the bottom end of the placement plate 3. The connecting plate 45 is slidably connected to the workbench 1. Four lifting rods 47 are symmetrically fixedly connected to the top of the connecting plate 45. Two second inclined blocks 46 are symmetrically fixedly connected to the bottom end of the connecting plate 45. Each first inclined block 43 slides against the bottom end of the second inclined block 46. Four extrusion holes 31 are opened through the interior of the placement plate 3. Each lifting rod 47 is located inside the extrusion hole 31. Four first limiting rods 44 are symmetrically fixedly connected to the top of the workbench 1. The first limiting rods 44 are used to position the placement plate 3.

[0029] It should be noted that two symmetrical fixed brackets 41 on the workbench 1 fix bidirectional electric push rods 42. The two telescopic ends of the bidirectional electric push rods 42 are connected to the first inclined block 43. Through the extension and retraction of the bidirectional electric push rods 42, the movement of the first inclined block 43 can be precisely controlled, and the power output can be flexibly adjusted. The first inclined block 43 slides against the second inclined block 46. When the first inclined block 43 moves, it can push the second inclined block 46 to move upward, thereby driving the connecting plate 45 and the lifting rod 47 to rise. This inclined block transmission method is stable and efficient, and can convert the horizontal movement of the electric push rod into the vertical movement of the lifting rod, so as to achieve the smooth lifting of the circuit board. The connecting plate 45 is slidably connected to the workbench 1, and four lifting rods 47 are fixed at the upper end. The four lifting rods 47 are located in the extrusion hole 31 of the placement plate 3, which can ensure that the lifting rods 47 accurately extrude the circuit board from the placement plate 3 during the rising process, and avoid the circuit board from getting stuck or scratched when it is taken out.

[0030] Working principle: The circuit board to be processed is placed on the top of the placement plate 3. At this time, the hydraulic push rod 51 in the limiting mechanism 5 is activated, and its telescopic end extends upward, driving the first fixed plate 511 and the movable roller 513 to move upward. During the upward movement of the movable roller 513, it squeezes the rotating blade 52. Since the rotating blade 52 is limited by the side plate 53, under the pressure of the movable roller 513, the end of the rotating blade 52 moves downward. The movable bracket 54, which is rotated and sleeved at the end of the rotating blade 52, moves accordingly, so that the arc-shaped connecting strip 55 and the rubber plate 56 can adjust the angle according to the arc movement of the rotating blade 52. Finally, the rubber plate 56 is parallel to the placement plate 3 and contacts the edge of the circuit board above the placement plate 3, realizing the flexible limitation of the circuit board and avoiding scratching the circuit board.

[0031] The tension spring 572 connects the first connecting frame 57 and the second connecting frame 571, which can buffer the impact of external forces and keep the rotating blade 52 stable. The second limiting rod 59 prevents the rotating blade 52 from moving too far downward. When the circuit board needs to be removed, the bidirectional electric push rod 42 in the lifting mechanism 4 is activated. Its two telescopic ends drive the first inclined block 43 to move. The first inclined block 43 pushes the second inclined block 46 to rise, which in turn drives the connecting plate 45 and the lifting rod 47 to rise. The lifting rod 47 extends out of the extrusion hole 31 and pushes the circuit board out smoothly. The first limiting rod 44 ensures that the position of the placement plate 3 is stable and ensures that the lifting process is smooth. The whole process realizes flexible contact, precise limiting and smooth ejection of the circuit board, effectively protecting the circuit board and improving production efficiency and product quality.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
