Special positioning disc for lead type electronic component reverse pasting machine

Abstract

The invention relates to the technical field of lead type electronic component production, in particular to a special positioning disc for a lead type electronic component reverse pasting machine. The special positioning disc comprises a mounting chassis, wherein a fixing disc is fixedly connected to the upper surface of the mounting chassis, a cover plate is arranged on the upper surface of the fixing disc, a fixing mechanism comprises four extension limiting blocks, four extension limiting grooves are formed in the lower surface of the cover plate, four built-in movable cavities are formed in the cover plate, clamping rods are slidably connected into the built-in movable cavities, and clamping grooves are formed in the surfaces of one sides of the extension limiting blocks. By arranging the fixing mechanism, the operation steps of: mounting or dismounting the cover plate and the fixing disc are simplified through the fixing mechanism, so that the cover plate does not need to be mounted in a bolt mode any more during mounting, the operation difficulty of workers is further reduced, meanwhile, the working intensity of workers when a dustproof cover is dismounted or mounted is reduced, and the efficiency of overhauling the structure in the fixed disc is guaranteed.

[0002] For a long time, low-speed reverse-mounting machines and high-speed reverse-mounting machines are usually used in the placement process of lead-type electronic components. These two structures will appear in the following situations during the design and production process: Low-speed reverse-mounting machines: low production speed , less than 150 pieces of products per minute, poor compatibility, difficult machine adjustment, high-speed anti-sticking machine (taping machine): fast production speed, up to 340 pieces per minute under normal circumstances, but the varistor is pulled out from the disk when it is reversed. When the upper body falls freely onto the stainless steel platform next to the re-posting plate, the product is easy to shift left and right, the product lead is tilted, and the height of the components after the re-posting is inconsistent, etc., resulting in frequent alarms of the equipment, a plummeting production capacity, and a sharp increase in the scrap rate. The compatibility is poor, so a special positioning plate is required. At the same time, the existing positioning plate for the lead-type electronic component anti-sticking machine cannot position and clamp electronic components of different sizes, and there is no dust cover, causing dust to enter the device. internal, affecting the accuracy of positioning of the device;

[0003] According to the above problems, the existing Chinese Patent Publication No.: CN112105252A discloses: a special positioning plate for a lead-type electronic component anti-sticking machine, which can prevent external dust from entering by setting a dust cover, a second bolt and a second threaded hole To the inside of the device, it affects the meshing of the ring rack and the helical gear inside the device, resulting in inconsistent extension lengths of the connecting shafts, making the device unable to perform precise positioning, but there are certain disadvantages in this solution: the dust cover in this solution It is installed with the fixed plate by bolts. When the installation structure in the fixed plate fails, it is necessary to remove the dust cover from the fixed plate to repair the structure in the fixed plate. As we all know, it is necessary to remove the bolts. A wrench is used, so that when removing the dust cover, the staff needs to first remove the bolts through the wrench, which seriously increases the difficulty of the staff's operation and increases the working strength of the staff when removing the dust cover , which affects the efficiency of structural maintenance in the fixed plate
