DETAILED DESCRIPTION

[0033] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1 and Figure 7 As shown, a correction structure for circuit board processing is provided, which includes a processing box 1, a dual-axis motor 2 is fixedly connected to the top of the processing box 1, the bottom end of the output shaft of the dual-axis motor 2 is located inside the processing box 1 and is fixedly connected to a worm 3, the inside of the processing box 1 is located on the left side of the worm 3 and is rotatably connected to a shaft 4 through a rotating shaft, the outer side wall of the shaft 4 is fixedly connected to a worm wheel 5, the worm wheel 5 is meshed with the worm 3, and the outer side wall of the shaft 4 is located in front and behind the worm wheel 5 and is fixedly connected to a sector gear 6;

[0036] Starting the dual-axis motor 2 can control the rotation of the worm 3, and then the worm 3 and the worm wheel 5 are meshed and connected, driving the fan-shaped gear 6 on the outer wall of the shaft 4 to rotate together, so that the teeth on the fan-shaped gear 6 can mesh with the rack 18 to move the pressure plate 1 7 and the pressure plate 2 8 down. When the teeth on the fan-shaped gear 6 are away from the rack 18, the spring 19 pulls the pressure plate 1 7 and the pressure plate 2 8 to return to the original position and rise.

[0037] like Figure 2 and Figure 4As shown, a pressure plate 1 7 and a pressure plate 2 8 are slidably connected in sequence from top to bottom inside the processing box 1, a placement plate 1 9 and a placement plate 2 10 are fixedly connected below the pressure plate 1 7 and below the pressure plate 2 8 inside the processing box 1, a connection frame 11 is symmetrically fixedly connected between the pressure plate 1 7 and the pressure plate 2 8, a plurality of springs 19 are fixedly connected between the processing box 1 and the pressure plate 1 7, a through-type through-hole 29 is provided on the upper surface of the placement plate 9 located on the outside of the two connection frames 11, a rack 18 is fixedly connected to the upper surface of the pressure plate 7 located on the left side of the two sector gears 6, the top of the rack 18 passes through to the top of the processing box 1 and is slidably connected to the processing box 1;

[0038] The upper surfaces of the placement plate 1 9 and the placement plate 2 10 are used to place multiple circuit boards. During the rotation of the sector gear 6, the pressure plate 1 7 can be intermittently pressed down by meshing with the rack 18. When the pressure plate 1 7 is pressed down, the pressure plate 2 8 will be driven to drop together, and the pressure on the pressure plate 1 7 is released. Under the pull of the spring 19, the pressure plate 1 7 and the pressure plate 2 8 are reset;

[0039] like Figure 8 As shown, the lower surface of the pressing plate 1 7 and the lower surface of the pressing plate 2 8 are both provided with a plurality of transverse plates 12, both ends of the transverse plates 12 are fixedly connected with sliding plates 13, the outer side wall of the sliding plate 13 is slidably connected with a pressure strip 14, the upper surface of the pressure strip 14 is symmetrically fixedly connected with a rotating connecting member 15 front and back, the outer side wall of the rotating connecting member 15 is rotatably connected with a connecting rod 16 through a rotating shaft, the top of the connecting rod 16 is rotatably connected with a rotating connecting member 2 17 through a rotating shaft, the tops of the plurality of rotating connecting members 2 17 are respectively fixedly connected to the lower surface of the pressing plate 1 7 and the lower surface of the pressing plate 2 8, a plurality of springs 20 are fixedly connected between the sliding plate 13 and the pressure strip 14, the right side of the processing box 1 is fixedly connected with an intelligent controller 21, and the lower surface of the pressure strip 14 is fixedly connected with an electric heating plate 22;

[0040] When the pressing plate 1 7 and the pressing plate 2 8 are lowered, they will drive multiple pressure strips 14 to descend together. Two adjacent pressure strips 14 are a group, which are used to level and correct a circuit board. When the adjacent pressure strips 14 descend, after contacting the circuit board, since the multiple pressure strips 14 are movably connected with the pressing plate 1 7 and the pressing plate 2 8 through the rotating connecting member 15, the rotating connecting member 2 17 and the connecting rod 16, when the bottom of the pressure strip 14 is blocked and the upper part continues to be pressed when the pressing plate 1 7 or the pressing plate 2 8 descends and is squeezed, the two adjacent pressure strips 14 will move back to each other, thereby realizing the leveling and correction of the circuit board. The pressure strip 14 heats the surface of the circuit board through the electric heating plate 22 at the bottom. Under the heating condition, the stress of the circuit board gradually relaxes, which is more convenient for the pressure strip 14 to be leveled by extrusion. When the pressure strips 14 rise with the pressing plate 1 7 and the pressing plate 2 8, under the pull of the spring 2 20 and the limit of the cross plate 12 and the sliding plate 13, the adjacent pressure strips will slide relative to each other and reset, and fit again, which is convenient for the next pressing.

[0041] like Figure 1 and Figure 3 As shown, the upper surface of the processing box 1 is located on the outer side wall of the dual-axis motor 2 and is fixedly connected to a box body 23, the top of the output shaft of the dual-axis motor 2 is fixedly connected to a fan blade 24, the upper surface of the box body 23 is located above the fan blade 24 and a filter screen 25 is detachably installed, both sides of the box body 23 are fixedly connected to the upper left side and the lower right side of the processing box 1 with exhaust pipes 26, the front surface of the processing box 1 is rotatably connected to a box door 27 through a hinge, and the front surface of the box door 27 is embedded with two filter screens 28;

[0042] When the dual-axis motor 2 rotates to control the pressure strip 14 to descend and level, the fan blades 24 will rotate together, thereby extracting the hot air inside the processing box 1 through the exhaust pipe 26, avoiding the problem of excessive temperature inside the processing box 1 when taking out the circuit board after subsequent processing is completed.

[0043] like Figure 5 and Figure 6 As shown, a contraction box 30 is fixedly connected to the rear surface of the processing box 1, and a contraction plate 31 is slidably connected to the inside of the contraction box 30. An electric telescopic rod 38 is fixedly connected between the contraction plate 31 and the contraction box 30. A push column 32 is symmetrically fixedly connected to the front surface of the contraction plate 31. The front ends of the two push columns 32 opposite to each other extend into the interior of the processing box 1 and are fixedly connected to a rear clamping plate 33. The two rear clamping plates 33 are respectively located above the placement plate 1 9 and the placement plate 2 10. The front of the upper surface of the placement plate 1 9 and the front of the upper surface of the placement plate 2 10 are fixedly connected with a threaded block 34. The internal threads of the threaded block 34 are connected with a threaded rod 35. The front end of the threaded rod 35 is fixedly connected with a knob 36. The rear end of the threaded rod 35 is rotatably connected to a front clamping plate 37 through a rotating shaft. The bottoms of the two front clamping plates 37 are in contact with the upper surface of the placement plate 1 9 and the upper surface of the placement plate 2 10 respectively.

[0044] When placing a circuit board, place it between the front clamping plate 37 and the rear clamping plate 33, and clamp the circuit board under the push of the electric telescopic rod 38. At the same time, the hand-held knob 36 can be used to control the threaded rod 35 to rotate inside the threaded block 34, and then the front clamping plate 37 can be controlled to move forward or backward, so that the distance between the front clamping plate 37 and the rear clamping plate 33 can be adjusted for circuit boards of different sizes, thereby achieving an effect of facilitating clamping.

[0045] like Figure 8 and Fig. 9As shown, the upper surface of the pressure strip 14 is symmetrically fixedly connected with a guide fixing block 39, and the upper surface of the pressure strip 14 is located on the right side of the guide fixing block 39 and is fixedly connected with a wedge-shaped extrusion block 40. A longitudinal guide rod 41 is fixedly connected between the two front and rear opposite guide fixing blocks 39, and a moving block 42 is slidably connected to the upper surface of the longitudinal guide rod 41. A rotating connecting piece 1 43 is fixedly connected to the upper surface of the moving block 42. A traction rod 44 is rotatably connected to the right side of the rotating connecting piece 1 43 through a rotating shaft. The top of the traction rod 44 is rotatably connected to a rotating connecting piece 2 45 through a rotating shaft. The tops of the two front and rear opposite rotating connecting pieces 2 45 are connected together. A transverse slider 46 is fixedly connected, and a U-shaped transverse guide rod 47 is slidably connected inside the transverse slider 46. The tops of the multiple U-shaped transverse guide rods 47 are respectively fixedly connected to the lower surface of the pressure plate 1 7 and the lower surface of the pressure plate 2 8. A knocking mounting piece 48 is fixedly connected to the right side of the moving block 42. A knocking rod 49 is slidably connected inside the knocking mounting piece 48. A push piece 50 is fixedly connected to the top of the knocking rod 49. A return spring 51 is sleeved on the outer wall of the knocking rod 49. The two ends of the return spring 51 are respectively fixedly connected to the push piece 50 and the opposite sides of the knocking mounting piece 48. A knocking ball 52 is fixedly connected to the bottom end of the knocking rod 49.

[0046] As the pressure strip 14 descends and contacts the circuit board, the two pressure strips 14 gradually separate, and the front and rear relative moving blocks 42 will slide back to back along the longitudinal guide rods 41 respectively. At this time, the pushed piece 50 will be blocked by multiple wedge-shaped extrusion blocks 40, and because the pushed piece 50 is movably connected to the knocking mounting piece 48 through the set return spring 51 and the knocking rod 49, it will rise after being blocked by the wedge-shaped extrusion block 40. When the pushed piece 50 moves away from the wedge-shaped extrusion block 40, it will drop and reset again under the pull of the return spring 51. Therefore, under the obstruction of multiple wedge-shaped extrusion blocks 40, as the front and rear relative moving blocks slide back to back, they can move up and down repeatedly, so that the knocking ball 52 can repeatedly knock the pressure strip 14, thereby playing the effect of assisting the pressure strip 14 to flatten the circuit board.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
