Power plug assembling method and assembling equipment

Technical Field

The invention relates to the field of power plugs, in particular to a power plug assembling method and assembling equipment.

Background

A power plug refers to a device that connects a device such as an electrical appliance to a power source. The power socket and the plug are different in appearance, grade, size and kind according to the region of the country, and each country has a standard set by the government. In the working process of the power plug, the top end of a contact pin of the power plug penetrates through the plastic shell to be connected with an external power supply system, the tail end of the contact pin is connected with an elastic sheet embedded in the plastic shell in an interference fit manner, and the elastic sheet is connected with an internal circuit system of the power plug; and the internal circuit system of the power plug is connected with the electrical components, so that the external power supply system is communicated with the electrical components connected with the power plug. When the quality of the power plug assembly is poor, the power supply of the electrical appliance connected with the power plug assembly is unstable, and even the service life of the electrical appliance is directly influenced. Therefore, the assembly quality of the power plug, which is an essential component for the electric appliance, is very important.

The Chinese intellectual property office discloses a patent publication No. CN206962234U, the patent name is a power plug assembling device, which comprises a plastic shell material box, a pin material box and a spring plate material tray, wherein the plastic shell, the pin and the spring plate are respectively conveyed to a rotary table on a main machine table; the elastic sheet is cut off and shaped from the elastic sheet belt at the elastic sheet cutting station, the elastic sheet is conveyed to a plastic shell taking and embedding station, the plastic shell is shifted to a pin assembling station after the elastic sheet is embedded into the plastic shell, and the plastic shell is shifted to a discharging station after the pin assembling station finishes pin embedding and the elastic sheet embedding, and falls into a discharging box. Compared with the prior art, the utility model discloses the productivity reaches 1300pCS every hour, need not manual operation moreover, full automatic control, and the equipment precision reaches 0.05 mm. The utility model discloses a full automatization power plug equipment, the efficient assembly of complete equipment is accurate, safety ring protects.

The prior art has the following defects: 1. when the elastic pieces are fed, the vibrating disc feeding mechanism feeds the two elastic pieces side by side, and then the two elastic piece moving mechanisms respectively move the two elastic pieces which are placed side by side to the same positions of two jigs which are aligned front and back to complete the feeding process of the elastic pieces side by side; the two elastic piece moving mechanisms are adopted to move the two elastic pieces respectively, so that the number of the elastic piece moving mechanisms is large, and the occupied space of the mechanisms is large; meanwhile, when the two elastic sheets are distributed side by side, the front and back directions of the two elastic sheets are not aligned, and when the two elastic sheets are moved to the same positions of the front and back aligned jigs, the front and back directions of the two elastic sheets need to be aligned; the elastic piece moving mechanism also needs to drive the elastic pieces which are distributed side by side to move along the left and right directions so as to align the front and back directions of the two elastic pieces, so that the elastic piece moving mechanism also needs a left and right direction moving assembly, and the complexity of the elastic piece moving mechanism is increased. 2. When the plastic shells are loaded, the plastic shells are moved to a single loading tray, and then the plastic shells in the loading tray are moved to corresponding jigs by the moving manipulator to complete plastic shell loading; the feeding tray is only single, and when the moving manipulator moves all the plastic shells in the single feeding tray, the empty feeding tray needs to be taken down firstly, and then the plastic shells are fed into the empty feeding tray again; in the process of feeding the plastic shell to the empty feeding tray, the moving manipulator is in a waiting state, and the plastic shell is moved in a stopping state, so that the time of the feeding process of the plastic shell is prolonged, and the plastic shell is not beneficial to quick feeding. 3. When the power plug is discharged, a single grabbing hand in the discharging grabbing mechanism drives the power plug to a detection station for appearance detection, and then the single grabbing hand moves the detected power plug to a discharging conveyor belt for discharging; a single grabbing hand in the blanking grabbing mechanism can move only one power plug at a time; when the power plug is detected at the detection station, the power plug assembled in the jig conveying device can only wait for the detection completion of the previous power plug and can be moved to the blanking conveying belt; therefore, two processes of waiting for the detection of the previous power plug and moving the previous power plug to the blanking conveyor belt are needed during blanking of the power plug, and the blanking efficiency of the power plug is reduced.

1. the elastic piece moving mechanism is arranged; after the vibrating disc feeding mechanism conveys the two elastic sheets to the pushing block groove side by side, the pushing cylinder acts to drive the inner pushing block and the outer pushing block to move to positions connected with the first suction head and the second suction head respectively; at the moment, the rolling bearing is contacted with the first inclined plane, and the second suction head is aligned with the outer elastic sheet; the up-down driving cylinder acts to drive the first suction head and the second suction head to move down to respectively suck the inner elastic sheet and the outer elastic sheet, and the front-back driving cylinder acts to drive the first suction head and the second suction head to move forward; the rolling bearing is in contact with the second inclined plane, the second suction head is aligned with the inner-side elastic sheet, and the first suction head and the second suction head move to corresponding hole positions of a jig in the jig conveying device to loosen the elastic sheet to complete the feeding process of the elastic sheet. The first suction head and the second suction head are controlled by the same elastic piece moving mechanism, namely the whole elastic piece moving process can complete the moving of two elastic pieces by only one elastic piece moving mechanism, so that the number of the elastic piece moving processes is reduced; meanwhile, the second suction head can be respectively aligned with the outer elastic sheet and the inner elastic sheet in a mode that the rolling bearings are respectively contacted with the first inclined surface and the second inclined surface in the movement process, so that the elastic sheets distributed side by side are moved to the front and back direction alignment positions; the driving device and the control device are not required to be arranged on the left and right directions of the elastic piece moving mechanism, and the complexity of the whole elastic piece moving mechanism is reduced.

2. Through arranging the staggered feeding mechanism; when the plastic shell in the first feeding disc is completely moved, the dislocation driving cylinder acts to drive the second feeding disc to move forwards to a position connected with the moving manipulator, and the first feeding disc moves backwards to a feeding port of the plastic shell; the second tray cylinder moves to drive the second tray receiving plate to move upwards, and the moving manipulator moves the plastic shell in the second tray receiving plate to move into a corresponding jig in the jig conveying device; meanwhile, the first feeding disc returning to the plastic shell feeding port is subjected to plastic shell circular feeding manually to complete the plastic shell feeding process. When the moving manipulator moves the plastic shell of any one mechanism of the first feeding tray or the second feeding tray receiving plate, the other mechanism carries out plastic shell feeding at a plastic shell feeding port; after the moving manipulator moves the plastic shell on the first feeding tray or the second feeding tray receiving plate, the plastic shell fed by the other mechanism can be immediately moved to a position connected with the moving manipulator for moving the moving manipulator; when the plastic shell is fed to an empty feeding tray, the moving manipulator moves the plastic shell in the other mechanism, so that the moving manipulator is always in a working state; therefore, the waiting condition of moving the manipulator when a single feeding disc is carried out is avoided, and the quick feeding of the plastic shell is ensured.

3. By arranging a blanking grabbing mechanism; after the jig conveying device conveys the assembled power plug to a blanking station, the grabbing driving assembly acts to drive the first grabbing hand and the second grabbing hand to move to positions above a blanking detection table and a corresponding jig of the jig conveying device respectively; the grabbing downward moving motor acts to drive the first grabbing hand and the second grabbing hand to move downward to grab the power plug at the position; the grabbing driving motor acts to drive the first grabbing hand to move the power plug which is detected in the blanking detection table to the blanking conveying belt for blanking, and meanwhile, the second grabbing hand moves the power plug which is assembled in the corresponding jig of the jig conveying device to the blanking detection table to detect and complete the blanking process of the power plug. In the whole blanking process, the detection of the assembled power plug and the blanking of the detected power plug are synchronously carried out, namely when the assembled power plug is moved to a detection station, the last detected power plug is moved to a blanking conveyor belt; therefore, the situation that a previous power plug needs to be waited for to detect and move when the power plug is discharged by a single grabbing hand is avoided, the two processes of detecting the assembled power plug and discharging the detected power plug can be always in a simultaneous operation state, and the discharging efficiency of the power plug is improved.

The blanking device 5 solves the problem that when the power plug is blanked, a single grabbing hand in the blanking grabbing mechanism firstly drives the power plug to a detection station for appearance detection, and then the single grabbing hand moves the detected power plug to a blanking conveying belt for blanking; a single grabbing hand in the blanking grabbing mechanism can move only one power plug at a time; when the power plug is detected at the detection station, the power plug assembled in the jig conveying device can only wait for the detection completion of the previous power plug and can be moved to the blanking conveying belt; therefore, two processes of waiting for the detection of the previous power plug and moving the previous power plug to the blanking conveyor belt are needed during blanking of the power plug, and the blanking efficiency of the power plug is reduced.

In the whole blanking process, the detection of the assembled power plug and the blanking of the detected power plug are synchronously performed, namely when the assembled power plug is moved to a detection station, the last detected power plug is moved to the blanking conveyor belt 53; therefore, the situation that a previous power plug needs to be waited for to detect and move when the power plug is discharged by a single grabbing hand is avoided, the two processes of detecting the assembled power plug and discharging the detected power plug can be always in a simultaneous operation state, and the discharging efficiency of the power plug is improved.
