Abstract
A transportation positioning device of a printed circuit board assembly (PCBA) comprises a base seat, wherein the base seat is provided with two guide rails which are arranged horizontally and used for transmission of a PCBA circuit board, the sides of the guide rails are respectively provided with a transmission mechanism which is driven by a stepping motor and composed of a driven wheel, a drive wheel, a tensioning wheel and a thin-type belt, the upper portions of the guide rails are respectively and fixedly provided with a left limiting plate and a right limiting plate, and a high-precision photoelectric inductive switch is installed on one of the guide rails. The driven wheels and the guide rails are arranged in a staggered mode, the front end and the rear end of each thin-type belt and each guide rail form an A-degree included angle, and an inclination angle B of 2-3 degrees is formed by the high-precision photoelectric inductive switch and the liner direction of the guide rail when the high-precision photoelectric inductive switch is installed, so that accurate positioning of the transported PCBA circuit board is guaranteed. The transportation positioning device of the PCBA has the advantages of being simple and reasonable in structure, capable of accurately positioning transported objects, free of the phenomenon of plate-clamping in the transportation process, and the like.
Description
Technical field
The utility model relates to the transmission positioning device of a kind of PCBA, particularly draw and PCBA wiring board transmission positioning device, belong to light-duty belt transport technical field.
Background technology
In the prior art, what transmission was adopted about PCBA is belt transport, and this belt transport exists some design defect, and such as the easy sideslip of belt, being transmitted object can not accurately locate, easy clamp etc. in the transmission course.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, can solve in the prior art that the transmission part is installed working accuracy is high and provide a kind of, being transmitted object can not accurately locate, the easy transmission positioning device of the PCBA of the problem such as clamp in the transmission course.
The purpose of this utility model is finished by following technical solution, it includes a pedestal, the guide rail for the transmission of PCBA wiring board of two horizontal is installed on the pedestal, the avris of guide rail is separately installed with the transmission device that is driven by stepping motor, be made of flower wheel, driving wheel, expansion tightening wheel and slim belt, the top of guide rail is fixed with respectively left limit plate and right limit plate, on the guide rail high precision photoelectric inductive switch is installed therein.
Flower wheel described in the utility model and guide rail arranged in dislocation, and make slim belt front and back end and guide rail form the angle of an A degree.
Described high precision photoelectric inductive switch has an angle of inclination B who becomes one 2-3 degree with the guide rail rectilinear direction when installing, can accurately locate to guarantee the PCBA wiring board that is transmitted.
The utlity model has simple and reasonable for structurely, can be transmitted object and accurately locate, can clamp in the transmission course etc. characteristics.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
Fig. 3 is continuous transmission structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the pedestal 10 that includes of the present utility model, the guide rail 8 for the transmission of PCBA wiring board of two horizontal is installed on the pedestal 10, the avris of guide rail 8 is separately installed with the transmission device that is driven by stepping motor 9, be made of flower wheel 1, driving wheel 3, expansion tightening wheel 2 and slim belt 4, the top of guide rail 8 is fixed with respectively left limit plate 5 and right limit plate 6, on the guide rail 8 high precision photoelectric inductive switch 9 is installed therein.
Flower wheel described in the utility model and guide rail arranged in dislocation, and make slim belt front and back end and guide rail form the angle of an A degree, as shown in Figure 2.
Described high precision photoelectric inductive switch has an angle of inclination B who becomes one 2-3 degree with the guide rail rectilinear direction when installing, can accurately locate to guarantee the PCBA wiring board that is transmitted, as shown in Figure 3.
Embodiment:
The utility model provides a kind of light-duty belt transmission device, by stepping motor 9, and high precision photoelectric inductive switch 7, slim belt 4, pedestal 10, guide rail 8, left limit plate 5, right limit plate 6, driving wheel 3, flower wheel 1, expansion tightening wheel 2 and screw form, described stepping motor and driving wheel are connected by screw, and belt connects by expansion tightening wheel by driving wheel and flower wheel transmission again. and photoelectric switch is fixed on guide rail one side.
The utility model has two flower wheels and guide rail arranged in dislocation, makes belt front and back end and guide rail form the angle of an A degree, and the rib of flower wheel just can be processed De Genggao like this, to prevent belt deviation.Traditional method was the parallel installation of flower wheel in the past, and this be just so that the flower wheel rib can not be higher than thickness of belt, otherwise belt can not drive and is transmitted object. therefore, the flower wheel rib is low, the just easy sideslip of belt, this just has higher requirement to precision and the form and position tolerance of part, sees Fig. 2.
The utility model is in the docking of two transmission units, and left limit plate and right limit plate all adopt the method for inclination angle guiding, and the PCBA wiring board is not easy clamp the transmission of turning left from the right side, see Fig. 3.
In design, adopt the high precision photoelectric inductive switch, for guaranteeing that being transmitted object can accurately locate, photoelectric switch will have the general 2-3 degree of certain angle of inclination B(when installing), can guarantee that so just the position that photoelectric switch detects is a specific angle point foremost that is transmitted object, see Fig. 3.
