Detailed implementation mode

[0029] The following further elaborates on the present utility model in conjunction with the embodiments, but the implementation modes of the present utility model are not limited thereto.

[0030] The present utility model provides a circuit board steering mechanism: its structure includes a conveying device 1 and a steering device 2. The steering device 2 is assembled on the side end face of the conveying device 1. The conveying device 1 is provided with side plates 11 and conveying rollers 12, and the conveying rollers 12 are assembled between the two side plates 11;

[0031] The conveying rollers 12 at the assembly position of the steering device 2 are shorter than the other conveying rollers 12;

[0033] The steering assembly seat b is composed of a top plate b1, a connecting side plate b2, and a bottom plate b3. The first pump rod g is assembled on the top of the bottom plate b3. The lower top plate f is assembled on the top of the first pump rod g. The limit assembly plate e is assembled inside the top plate b1. The limit assembly plate e is fixedly connected concentrically with the upper pressing plate d through a shaft rod penetrating the bottom of the top plate b1. There is an empty groove between the upper pressing plate d and the bottom of the top plate b1. The hinge connecting shaft c is arranged on the top side of the upper pressing plate d. An induction device h is assembled between the lower top plate f and the conveying rollers 12. One end of the second pump rod i is hinged to the top pressing assembly plate a, and the other end of the second pump rod i is hinged to the upper pressing plate d through the hinge connecting shaft c.

[0034] Among them, the lower top plate f is directly below the upper pressing plate d.

[0035] Among them, the bottom of the upper pressure plate d is higher than the top of the conveying roller 12, and the top of the lower top plate f is lower than the top of the conveying roller 12 when it is at the lowest position.

[0036] Among them, the limiting assembly plate e is a circular plate.

[0037] Among them, it further includes an assembly frame 3 and a cover plate 4. The conveying device 1 is assembled in the assembly frame 3, and the periphery of the assembly frame 3 except for the conveying device 1 is covered by the cover plate 4.

[0038] Among them, the induction device h is composed of a detection connecting plate h1, a detection wheel h2, a detection limiting groove h3, a pressure sensor h4, a detection seat h5, and a limiting connecting plate h6. The detection connecting plate h1 and the detection wheel h2 are coaxially assembled with the conveying roller 12 on the side where the opening of the steering assembly seat b faces. A limiting connecting plate h6 is fixed to the bottom of the detection connecting plate h1. The detection seat h5 is fixed to the cover plate 4 below the assembly position of the detection connecting plate h1. A detection limiting groove h3 is provided at the top of the detection seat h5, and a pressure sensor h4 is assembled at the bottom of the detection limiting groove h3. The bottom of the limiting connecting plate h6 is inserted into the detection limiting groove h3 and is in contact with the top of the pressure sensor h4.

[0039] Among them, the top of the detection wheel h2 is slightly higher than the top of the conveying roller 12.

[0040] Among them, it further includes a lifting structure j and a hinge seat k. The lifting structure j is used to adjust the assembly height of the steering assembly seat b. The hinge seat k can be slidably assembled up and down on the top pressing assembly plate a, and the hinge seat k is hinged to the side of the second pump rod i away from the upper pressure plate d.

[0041] Among them, the lifting structure j is composed of an adjusting shaft j1, a lifting limiting groove j2, a threaded groove j3, a lifting connecting plate j4, a motor j5, a gear j6, and a lifting assembly plate j7. A lifting connecting plate j4 is fixed to the side of the steering device 2 away from the conveying roller 12. The lifting assembly plate j7 is fixed to the side plate 11 of the steering device 2 away from the conveying roller 12. A lifting limiting groove j2 is provided on the side of the lifting assembly plate j7 adjacent to the steering device 2. An adjusting shaft j1 is vertically assembled in the lifting limiting groove j2. A threaded groove j3 is provided on the part of the adjusting shaft j1 located in the lifting limiting groove j2. The lifting connecting plate j4 is arranged in the lifting limiting groove j2 and wraps the adjusting shaft j1. The lifting connecting plate j4 is threadedly connected to the threaded groove j3. The lifting connecting plate j4 cannot rotate in the lifting limiting groove j2. The bottom of the adjusting shaft j1 is connected to the motor j5 through the gear j6.

[0042] Embodiment 1: During use, place the circuit board on the conveying roller 12 of the conveying device 1. As the conveying roller 12 conveys, the circuit board will enter the range of the steering device 2. The circuit board will first press against the detection wheel h2 that is slightly higher than the conveying roller 12. The detection wheel will press against the pressure sensor h4 through the limit connecting plate h6 to trigger a signal, causing the controller (not shown in the figure) to control the first pump rod g to drive the lower top plate f to rise, so that the upper pressing plate d and the lower top plate f clamp a corner of the circuit board. Then, the controller (not shown in the figure) controls the second pump rod i to extend. Since both ends of the second pump rod i are hinged and limited, when the second pump rod i extends, it will drive the upper pressing plate d to rotate along the center of the circle, so that the circuit board can be driven to rotate by ninety degrees, thus realizing the steering function;

[0043] In order to reduce the situation that when clamping circuit boards of different thicknesses, the clamped corner is lifted too high, resulting in the circuit board being bent due to the steering force and gravity in subsequent processes, the steering device 2 of the mechanism is also provided with a lifting structure j for adjusting the clamping height. During adjustment, the controller (not shown in the figure) controls the motor j5 to drive the threaded groove j3 to rotate. Since the threaded groove j3 is limited and the lifting connecting plate j4 threadedly connected to the threaded groove j3 cannot rotate, the lifting connecting plate j4 will drive the steering assembly seat b to lift as a whole, thus realizing the problem of being able to adjust the clamping height, which is convenient for clamping and steering the use of circuit boards of different thicknesses.

[0044] Embodiment 2: During use, with the other structures unchanged, the structure in which the lifting structure j drives the lifting connecting plate j4 to lift through the motor j5, the gear j6, and the adjusting shaft j1 can be replaced with a third pump rod l to drive the lifting connecting plate j4 to lift, and the achieved effect remains the same.

[0045] Embodiment 3: During use, with the other structures unchanged, the structure in which the induction device h detects the circuit board through the detection connecting plate h1, the detection wheel h2, the detection limit groove h3, the pressure sensor h4, the detection seat h5, and the limit connecting plate h6 can be replaced with a photoelectric sensor m, and the achieved effect remains the same.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

The wiring diagram of the power element and the power supply are common knowledge in the art, and the present invention is mainly used to protect mechanical devices, so the control mode and wiring layout of the present invention will not be explained in detail.
