Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit board processing, in particular to a patch device for preventing dislocation. Background Art

[0002] An integrated circuit board is a miniature electronic device or component. It uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit. It is made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. At the same time, the patch process is also required in the processing of integrated circuit boards.

[0003] At present, the patching of integrated circuit boards is usually done manually. During the patching, the integrated circuit board is pressed down and fixed by one hand, and then the surface of the circuit board is patched with the other hand. However, manual fixation is OK for small-sized integrated circuit boards, but it is easy to fix the integrated circuit boards with slightly larger sizes unstably, so that the patching will be misplaced, which affects the patching quality of the integrated circuit board and makes the patching efficiency low. The existing patching device for the circuit board cannot be well adjusted and fixed for circuit boards of different sizes, and is inconvenient to use. Therefore, we propose a patching device that prevents misalignment. Utility Model Content

[0006] Preferably, fixed plates are symmetrically fixedly connected at both ends of the bottom of the base plate, and a bidirectional screw is rotatably connected between the two fixed plates. Sliding rods are symmetrically threaded at both ends of the bidirectional screw. Guide grooves are symmetrically opened at both ends of the top of the base plate, and both ends of the sliding rod pass through the guide grooves and are fixedly connected to the first positioning plate.

[0007] Preferably, the top of the bottom plate is symmetrically provided with limiting grooves, the bottom of the second positioning plate is integrally provided with a limiting block, and the limiting block is slidably connected in the limiting groove.

[0008] Preferably, the height of the connecting rod is smaller than the height of the first positioning plate, and the bottom of the first positioning plate is symmetrically provided with sliding grooves, and the sliding grooves are slidably connected to the outside of the connecting rod.

[0009] Preferably, the end of the bidirectional screw passes through a fixing plate and is fixedly connected to a worm wheel. The fixing plate is symmetrically fixedly connected to a mounting plate on one side of the worm wheel, and a worm is rotatably connected between the two mounting plates. The worm and the worm wheel are meshingly connected. A handle is rotatably connected to the top of the mounting plate, and the top of the worm passes through the mounting plate and is fixedly connected to the handle.

[0010] Preferably, connecting plates are symmetrically and integrally connected to both ends of the bottom plate, and vertical mounting holes are provided on the tops of the connecting plates.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: an anti-misalignment patch device, including a base plate 1, fixed rods 2 are symmetrically fixedly connected at both ends of the top of the base plate 1, a connecting rod 3 is symmetrically fixedly connected between the two fixing rods 2 at the top of the base plate 1, a first positioning plate 4 is symmetrically slidably connected between the two fixing rods 2 at the top of the base plate 1, threaded holes are provided on the side walls of the two connecting rods 3, and threaded rods 5 are threadedly connected in the threaded holes, one end of the threaded rod 5 is fixedly connected to a second positioning plate 6, the second positioning plate 6 is slidably connected to the top of the base plate 1, and the other end of the threaded rod 5 is fixedly connected to a turning handle 19.

[0022] It should be noted that when the utility model is used, the four connecting plates 16 on the bottom plate 1 are first fixedly installed on the operating plane by fixing screws, so that one end of the screw handle 15 is away from the operator, and the fixing rod 2 at the other end is close to the operator. After installation, the two turning handles 19 are located on both sides of the operator's hands, and the integrated circuit board to be patched is placed at the top center of the bottom plate 1. The hand turns the screw handle 15 to rotate the worm 14, and the two-way screw 8 is rotated through the meshing connection between the worm 14 and the worm wheel 12. The two sliding rods 9 are threadedly connected to the two ends of the two-way screw 8, so that the two first positioning plates 4 are simultaneously approached to the circuit board until the two first positioning plates 4 are clamped on the corresponding two sides of the circuit board, and then the turning handles 19 on both sides are rotated to rotate the threaded rod 5, and the second positioning plate 6 is horizontally moved through the threaded connection between the threaded rod 5 and the inner threaded hole of the connecting rod 3, and the two second positioning plates 6 are controlled to respectively press against the other two sides of the integrated circuit board, so that the four side walls of the circuit board are firmly fixed, thereby ensuring the stability of the circuit board position and making the patch more accurate.

[0023] The two ends of the bottom of the base plate 1 are symmetrically fixedly connected with fixed plates 7, and a bidirectional screw 8 is rotatably connected between the two fixed plates 7. The two ends of the bidirectional screw 8 are symmetrically threaded with sliding rods 9. The two ends of the top of the base plate 1 are symmetrically provided with guide grooves 10, and the two ends of the sliding rod 9 pass through the guide grooves 10 and are fixedly connected to the first positioning plate 4.

[0024] It should be noted that by controlling the rotation of the bidirectional screw 8, the two sliding rods 9 can be controlled to approach or move away from each other, thereby controlling the two sliding rods 9 to move toward the center of the base plate 1 at the same time, driving the two first positioning plates 4 to approach the circuit board at the same time, so that the two first positioning plates 4 clamp and fix the two sides of the circuit board, so that the integrated circuit board is firmly positioned.

[0025] The top of the bottom plate 1 is symmetrically provided with a limiting groove 11 , and the bottom of the second positioning plate 6 is integrally provided with a limiting block, and the limiting block is slidably connected in the limiting groove 11 .

[0026] It should be noted that during the sliding process of the second positioning plate 6, the limit block on the second positioning plate 6 slides inside the limit groove 11 on the base plate 1, which can ensure the accurate alignment between the base plate 1 and the second positioning plate 6 and ensure the smooth movement of the second positioning plate 6.

[0027] The height of the connecting rod 3 is smaller than that of the first positioning plate 4 . The bottom of the first positioning plate 4 is symmetrically provided with sliding grooves 18 , and the sliding grooves 18 are slidably connected to the outside of the connecting rod 3 .

[0028] It should be noted that during the movement of the first positioning plate 4, the connecting rod 3 is always located in the slide groove 18 of the first positioning plate 4, and the first positioning plate 4 is slidably connected to the outside of the two connecting rods 3, so that the first positioning plate 4 can move smoothly toward the circuit board.

[0029] The end of the bidirectional screw 8 passes through the fixing plate 7 and is fixedly connected to a worm wheel 12. The fixing plate 7 is symmetrically fixedly connected to a mounting plate 13 on one side of the worm wheel 12. A worm 14 is rotatably connected between the two mounting plates 13. The worm 14 and the worm wheel 12 are meshingly connected. A handle 15 is rotatably connected to the top of the mounting plate 13. The top of the worm 14 passes through the mounting plate 13 and is fixedly connected to the handle 15.

[0030] It should be noted that the worm 14 is rotated by turning the handle 15, and the bidirectional screw 8 is rotated through the meshing connection of the worm 14 and the worm wheel 12. The two sliding rods 9 are threadedly connected to the two ends of the bidirectional screw 8 to make the two first positioning plates 4 approach the circuit board at the same time until the two first positioning plates 4 are clamped on the corresponding two sides of the circuit board. The matching arrangement of the worm 14 and the worm wheel 12 has a high self-locking property, so that the two first positioning plates 4 can firmly clamp the circuit board, which is conducive to precise patch.

[0031] The two ends of the bottom plate 1 are symmetrically connected to the connecting plate 16, and the top of the connecting plate 16 is provided with a vertical mounting hole 17.

[0032] It should be noted that by arranging four connecting plates 16 at the bottom of the base plate 1, the connecting plates 16 can be fixed on the supporting surface by bolts, making the device as a whole more stable. When not in use, the device can be directly taken and transferred, and it is also very convenient to carry.

[0033] The bottom plane height of the connecting plate 16 is lower than the bottom plane height of the fixing plate 7 .

[0034] It should be noted that when the connecting plate 16 is installed on the supporting plane by fixing bolts, the height of the bottom plane of the connecting plate 16 is set lower than the height of the bottom plane of the fixing plate 7, so that the bottom of the connecting plate 16 can be in contact with the supporting plane, so that the connecting plate 16 is fixedly installed by fixing screws, thereby ensuring the overall stability of the device.
