Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production and processing, in particular to a positioning device for circuit board processing. Background Art

[0002] With the development of society, intelligence is used in many places. The operation of intelligence is inseparable from the operation of circuit components. Circuit boards have been increasingly valued by various manufacturers. The quality of the produced circuit boards depends on the precision of each component on the circuit board. The higher the precision, the smaller the volume of the corresponding circuit board. At the same time, the more functions there are on the same circuit board. When the circuit board and the laminated cover are produced and processed, they need to be positioned;

[0003] In the prior art, the Chinese utility model with publication number: CN218277323U discloses a positioning device for circuit board processing, which belongs to the technical field of circuit board processing. It solves the problem that in order to ensure the stability of the circuit board during processing, the circuit board needs to be positioned. Generally, a limit plate is used to clamp and position the circuit board. However, when the limit plate is used for a long time, its clamping surface will be worn to varying degrees, resulting in a reduction in the positioning effect of the limit plate on the circuit board, which further leads to a poor positioning effect on the circuit board, and easily causes the circuit board to fall off during processing. The device includes a processing table, a groove is provided on the top of the processing table, a circuit board body is provided above the processing table, and a limit mechanism is provided on both sides of the circuit board body. By providing a limit mechanism for installing and fixing the circuit board body, the positioning of the circuit board body during processing is improved, thereby improving the positioning effect of the circuit board body, and making the circuit board body less likely to fall off;

[0004] The above technical solution improves the positioning of the circuit board during processing, but requires multiple limit mechanisms to rotate and position the four ends of the circuit board, which is more complicated to operate and increases the positioning time of the circuit board. Therefore, we need to propose a positioning device for circuit board processing. Utility Model Content

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.

[0023] See also Figure 1-3The utility model provides a technical solution: a positioning device for processing a circuit board, comprising a base 1, two sets of fixing mechanisms 4 are symmetrically arranged on the upper surface of the base 1, and positioning mechanisms 5 are arranged in both sets of fixing mechanisms 4;

[0024] The fixing mechanism 4 includes a vertical plate 41, a bottom plate 42 and a top plate 43 are welded to two ends of one side of the vertical plate 41, a first pad 44 is bonded to the upper surface of the bottom plate 42, and the positioning mechanism 5 is arranged directly below the bottom plate 42, two groups of first limiting holes 431 are symmetrically opened on the upper surface of the top plate 43, a second limiting hole 432 is opened on the upper surface of the top plate 43, and a guide hole 433 is opened on the side wall of the second limiting hole 432;

[0025] The positioning mechanism 5 includes a positioning plate 53, a movable rod 51 and two groups of limiting rods 55 arranged between the bottom plate 42 and the top plate 43. The lower ends of the two groups of limiting rods 55 respectively pass through the two groups of first limiting holes 431 and are fixedly connected to the upper surface of the positioning plate 53. A hinge seat 532 is fixedly connected to the middle part of the upper surface of the positioning plate 53. The lower end of the movable rod 51 passes through the second limiting hole 432 and is hinged to the hinge seat 532. A guide protrusion 511 is integrally formed on the upper end of the outer side of the movable rod 51, and a spring 52 is sleeved on the outer side of the movable rod 51.

[0026] When in use, pull the pull rings 512 of the two sets of positioning mechanisms 5 to pull the limiting protrusions on the outer side of the movable rod 51 out of the guide hole 433 and rotate it within a certain range, and use the movable rod 51 to contact the outer side of the upper end of the second limiting hole 432 through the limiting protrusion, so as to position the height of the positioning plate 53. At this time, the spring 52 is in a compressed state, and at the same time, the two sets of limiting rods 55 are slidably connected in the first limiting hole 431, which improves the stability of the positioning plate 53 when it is lifted or lowered. The adjusting disk 3 is rotated to drive the threaded rod 31 to rotate, so that the threaded rod 31 is threadedly connected to the threaded through hole of the first slider 421, driving the bottom plate 42 to move along the direction of the first slide groove 101. The two sets of second sliders 422 improve the stability of the bottom plate 42 when it moves. By rotating the adjusting disk 3, the spacing between the two sets of fixed components can be adjusted to facilitate the placement of circuit boards of different specifications, thereby increasing the scope of application. The lower surface of the circuit board contacts the first pads 44 of the two sets of positioning mechanisms 5. At the same time, the two sets of pull rings 512 are pulled and rotated to fit the limiting protrusion on the outer side of the upper end of the movable rod 51 with the guide hole 433.

Two groups of second reinforcing ribs 531 are integrally formed on the upper surface of the positioning plate 53. The hinge seat 532 and the two groups of limiting rods 55 are all arranged between the two groups of second reinforcing ribs 531. The second pad 54 and the first pad 44 protect the surface of the circuit board, reduce the wear of the circuit board caused by positioning, and increase the service life of the circuit board. At the same time, the second reinforcing ribs 531 increase the overall strength of the positioning plate 53 to prevent the positioning plate 53 from bending due to long-term use.

[0029] A plurality of first reinforcing ribs 411 are integrally formed on the other side of the vertical plate 41, and the plurality of first reinforcing ribs 411 are arranged at equal intervals. A plurality of supporting blocks 412 are welded to one end of the lower surface of the top plate 43 close to the vertical plate 41, and the plurality of supporting blocks 412 are arranged at equal intervals. The strength of the vertical plate 41 is improved by the plurality of first reinforcing ribs 411, and the service life of the fixing mechanism 4 is increased. At the same time, the plurality of supporting blocks 412 increase the firmness of the top plate 43, and prevent the top plate 43 from tilting due to long-term use.

[0030] A first slider 421 and two groups of second sliders 422 are welded to the lower surface of the base plate 42. A threaded through hole is opened on one side of the first slider 421. The two groups of second sliders 422 are symmetrically arranged. The first slider 421 is arranged between the two groups of second sliders 422. The stability of the fixing mechanism 4 during movement is improved by the first slider 421 and the two groups of second sliders 422.

[0031] Both ends of the upper surface of the base 1 are provided with first slide grooves 101 for sliding connection of the first slider 421, and both ends of the upper surface of the base 1 are provided with second slide grooves 102 for sliding connection of two groups of second sliders 422.
