Abstract
The utility model discloses a chip mounter is with pressing from both sides formula abnormal shape suction nozzle relates to paster plug-in components technical field, the utility model overcomes because plug-in components machine translation rate is fast, produce material center and suction nozzle center skew, rotation easily, lead to the unable accuracy of material pin to insert PCB diaphragm orifice and paste the problem bad or the material can not hold and drop and throw the material, the following scheme of now proposed: the suction nozzle comprises a suction nozzle rod, the suction nozzle rod is installed at the center of the bottom of the suction nozzle, an arc-shaped groove is formed in the nozzle head of the suction nozzle rod, an air opening hole is formed in the center of the suction nozzle rod, the arc-shaped groove is matched with the material suction surface in shape, pins are arranged at two ends of the material, and clamping jaws are arranged on two sides of the suction nozzle. The utility model discloses an increase the clamping jaw in suction nozzle both sides, after the suction nozzle absorbs the material, the throwing material rate of material has reduced 0.05% from 2% at quick travel and fast rotation in-process material. The deviation defective rate of the material center and the suction nozzle center is reduced from 3 percent to 0.1 percent. Greatly reduces the reject ratio and leads the product percent of pass to reach more than 99 percent.
Description
Technical Field
The utility model relates to a paster plug-in components technical field especially relates to a paster machine presss from both sides formula abnormal shape suction nozzle.
Background
Chip mounter: also known as a mounter or a Surface Mount System (Surface Mount System), which is disposed behind a dispenser or a screen printer in a production line, is an apparatus for accurately placing Surface Mount components on PCB pads by moving a mounting head. The method is divided into manual operation and full-automatic operation.
In the existing method for sucking the materials in the diode, an air hole is formed in the middle of a suction nozzle rod in a suction nozzle sucking mode to suck the materials in a vacuum mode. Because the plug-in components machine moves fastly, still quick turned angle when quick removal. The material center and the center of the suction nozzle are easy to deviate and rotate, so that the pins of the material cannot be accurately inserted into holes of the PCB to be poorly attached or the material cannot be sucked, dropped and thrown.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that because the plug-in components machine translation rate is fast, still can quick turned angle simultaneously at the quick travel. The material center and the suction nozzle center are easy to deviate and rotate, so that the pins of the material cannot be accurately inserted into holes of a PCB (printed circuit board) for poor mounting or the material cannot be sucked, fall and be thrown, and in order to solve the technical problem, the clamp type special-shaped suction nozzle for the chip mounter is provided, and comprises a suction nozzle;
the suction nozzle comprises a suction nozzle rod, the suction nozzle rod is installed at the center of the bottom of the suction nozzle, an arc-shaped groove is formed in the head of the suction nozzle rod, an air opening hole is formed in the center of the suction nozzle rod, the arc-shaped groove is matched with the shape of a material suction surface, pins are arranged at two ends of the material, clamping jaws are arranged on two sides of the suction nozzle, and long grooves are formed in the inner side walls of the clamping jaws.
Preferably, the width of the long groove is the same as the length of the outer diameter of the pin.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses increased the clamping jaw in suction nozzle both sides, after the suction nozzle absorbs the material, fallen 0.05% from 2% at the throwing material rate of quick travel and fast rotation in-process material. The deviation defective rate of the material center and the suction nozzle center is reduced from 3 percent to 0.1 percent. Greatly reduces the reject ratio and leads the product percent of pass to reach more than 99 percent. The production cost of the product is reduced, the production efficiency is improved, and certain economic benefits are brought to companies.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Reference numbers in the figures: 1 suction nozzle, 2 suction nozzle rods, 21 arc-shaped grooves, 3 clamping jaws, 31 long grooves, 4 materials and 41 pins.
Detailed Description
The invention is further described with reference to the accompanying drawings and examples.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1, a clip-on special-shaped suction nozzle for a chip mounter includes a suction nozzle 1;
the suction nozzle 1 comprises a suction nozzle rod 2, the suction nozzle rod 2 is installed at the center of the bottom of the suction nozzle 1, an arc-shaped groove 21 is formed in the head of the suction nozzle rod 2, an open air hole is formed in the center of the suction nozzle rod 2, the arc-shaped groove 21 is matched with the shape of a material 4 suction surface, pins 41 are arranged at two ends of the material 4, clamping jaws 3 are arranged on two sides of the suction nozzle 1, and long grooves 31 are formed in the inner side walls of the clamping jaws 3.
For better absorption material, the utility model discloses still include elongated slot 31 width is the same with pin 41 external diameter length.
The working principle is as follows: the utility model discloses increase clamping jaw 3 in 1 both sides of suction nozzle, clamping jaw 3 inboard is opened the elongated slot 31 the same with pin 41 external diameter. The pins 41 of the clamping jaws 3 for clamping the materials 4 are increased, and the friction force of the clamping jaws 3 is increased when the materials 4 are not only sucked by the nozzle rod 2. The acting force between the suction nozzle 1 and the material 4 is increased, and the risk that the material falls off when the suction nozzle 1 and the material 4 move and rotate quickly is reduced. The long groove 31 on the inner side of the clamping jaw 3 can just hold the pin 41 of the material 4, so that the positioning and orienting functions are realized. When the suction nozzle 1 and the material 4 move and rotate rapidly, the center of the material 4 is not easy to deviate and rotate from the center of the suction nozzle 1.
The above-mentioned embodiments only express the preferred embodiments of the present invention, and the description thereof is more specific and detailed, but the present invention is not limited to these embodiments, and it should be noted that it is obvious to those skilled in the art. Without departing from the spirit of the present invention, any improvement is within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
