[0046] The utility model discloses a kind of movement mechanism can be respectively grabbed the mode of two different devices, provide a kind of process of two different devices combination welding together, simplify movement mechanism and improve production efficiency.Its process mainly includes five steps:1, place the tray of shell 64, upper ferrule sleeve tray 47, lower product tray 44;2, ferrule sleeve 38 automatic cap off loading;3, ferrule sleeve 38 ferrule direction identification;4, upper shell 64 welding;5, lower product 28.Shell 64 filled tray and upper ferrule sleeve tray 47 filled with ferrule sleeve 38 and empty lower product tray 44 are fixed in position using elbow clamp 46, gripper suction nozzle switching cylinder 41 on gripper suction mechanism 18 of mechanical hand is stretched downwards, ferrule sleeve gripper 39 can be placed in chuck 23 at this time ferrule sleeve 38 with protective cap 61 is grabbed and clamped, then ferrule sleeve gripper 39 is opened and lifted to a certain height again and clamped, ferrule sleeve gripper 39 is lifted upwards, the separation of the root of protective cap 61 and the upper end part of ferrule sleeve 38 can be completed, top camera mechanism 6 is then collected the direction of crescent in ferrule, then rotating mechanism rotates ferrule sleeve 38 to the set qualified angle, side camera mechanism 16 confirms whether the direction of mark point 63 on the cylindrical surface of ferrule sleeve 38 is consistent with the direction of crescent identified by top camera mechanism 6, gripper suction mechanism 18 of mechanical hand moves to the upper of shell 64, gripper suction nozzle switching cylinder 41 is retracted upwards, and shell suction nozzle 32 can suction shell 64 upper surface, then move to the upper of ferrule sleeve 38, and shell is placed in ferrule sleeve 38 for welding first gun, then rotating mechanism rotates 15 ° in positive and negative, and second, third guns are welded, rotating mechanism is finally rotated to the angle when upper shell, and shell upper surface is suctioned by gripper suction nozzle 32 of gripper suction mechanism 18 of mechanical hand, and the chuck 23 below clamping ferrule sleeve is loosened, and gripper suction mechanism 18 of mechanical hand moves to the position of lower product mechanism 17, and is placed in lower product tray 44, so that the welding of one product 28 is completed, and subsequent reciprocation can be carried out.

[0047] The working process of the ferrule sleeve and shell full-automatic welding equipment includes the following steps: ​​

[0048] Step one, place the shell 64 tray, the upper core sleeve tray 47, the lower product tray 44:

[0049] Place the tray filled with shell 64 in the shell placement Y-axis mechanism 8 in the fixed direction, fix the position with elbow clamp 46, and place the upper core sleeve tray 47 filled with core sleeve 38 with protective cap 61 in the upper core sleeve mechanism 14, fix the position with elbow clamp 46, place the empty lower product tray 47 in the lower product mechanism 17, fix the position with elbow clamp 46, and the preparation work is completed.

[0050] Step two, automatic cap removal and core sleeve loading:

[0051] The mechanical hand suction gripper mechanism 18 on the four-axis mechanical hand 11 will go to the upper core sleeve mechanism 14 position, the gripper suction nozzle switching cylinder 41 in the mechanical hand suction gripper mechanism 18 will extend downward, at this time the core sleeve gripper 39 can grab the core sleeve 38 with protective cap 61, because the root of the protective cap 61 is tightly attached to the upper end of the core sleeve 38, the core sleeve gripper 39 can clamp the root of the protective cap 61 to clamp and take out together, and place it in the chuck mechanism, the chuck 23 clamps the lower end of the core sleeve 38, the core sleeve gripper 39 loosens and clamps upward by a certain height, so that the head of the protective cap 61 can be grabbed, because the lower end of the core sleeve 38 is clamped by the chuck 23, at this time the head of the protective cap 61 is clamped by the core sleeve gripper 39, only the core sleeve gripper 39 needs to be lifted upward, and the separation of the root of the protective cap 61 and the upper end of the core sleeve 38 can be completed, then the mechanical hand suction gripper mechanism 18 is moved to the cap dropping position, the core sleeve gripper 39 is opened, and the protective cap 61 is dropped into the waste cap box 13.

[0052] Step three, core sleeve 38 core insertion direction identification:

[0053] After the core sleeve 38 is fixed and the protective cap 61 is removed, the top camera mechanism 6 collects the direction of the crescent moon in the core, then the rotating mechanism rotates the core sleeve 38 to the set qualified angle, the side camera mechanism 16 confirms whether the direction of the mark point 63 on the cylindrical surface of the core sleeve 38 is consistent with the direction of the crescent moon identified by the top camera mechanism 6, and waits to be placed into the shell 64 for welding.

[0054] Step four, welding in the upper shell 64:

[0055] The Y-axis mechanism 8 in the upper shell mechanism places the row of full shell 64 that the switching mechanism switches, and each row is in a straight line with the shell pushing X-axis mechanism 9 and the shell overturning mechanism 10. The shell pushing X-axis mechanism 9 pushes the shell 64 to the position of the shell overturning tool 51 in the shell overturning mechanism 10, and then the shell 64 is stood up by being sucked by vacuum and being overturned by 90°. After the shell 64 is separated and overturned, the suction gripper mechanism 18 of the manipulator moves above the shell 64, the suction nozzle switching cylinder 41 is retracted upwards, the shell suction nozzle 32 can suck the upper surface of the shell 64, then moves above the plug sleeve 38, and the shell 64 is placed in the plug sleeve 38. The 120°-divided welding gun 12 performs first gun welding, then the rotating mechanism rotates by 15° in positive and negative directions, the second and third guns are welded, and finally the rotating mechanism rotates back to the angle of the upper shell, so that the shell suction nozzle 32 can be unloaded. The plug sleeve 38 is below, the shell 64 is above, and the three 120°-direction welding guns are assembled and welded in reverse, which has the advantages that the plug sleeve 38 is a cylinder, which is convenient for clamping and adjusting concentricity relative to the cuboid shell 64; the direction is convenient for rotating by collecting images from above; and the welding needs to be welded at 9 points in 3 positions that are evenly divided in 120° directions and are positive and negative by 15°, so that the rotating concentricity is high.

[0056] Step five, the lower product 28:

[0057] The product 28 after welding is sucked from the upper shell by the shell suction nozzle 32 of the manipulator suction gripper mechanism 18, the lower clamping plug sleeve chuck 23 is loosened, the manipulator suction gripper mechanism 18 moves to the lower product mechanism 17 position, and is placed in the lower product tray 44, so that the welding of one product 28 is completed, and the subsequent steps two to five are repeated.

[0058] The difference between the utility model and the background art is:

[0059] (1) The background art is manually semi-automatically welded, and the whole process needs to be controlled by people, such as feeding and discharging, confirming the product direction, and confirming the welding position for welding. In this way, the efficiency is very low, and the welding quality cannot be controlled. The utility model realizes full-automatic welding of the plug sleeve and the shell, only needs to replace the feeding and discharging trays, does not need human intervention in the whole welding process, saves one person per machine, and the welding time is shortened by one time and the efficiency is doubled.

[0060] (2) Background Art The welding method is backward: the shell is placed below, and the plug-in core sleeve is placed above. Since the plug-in core sleeve is a cylinder, and the shell is mostly a cuboid, it is difficult to adjust the welding three-part degree and the rotational concentricity, and it is unstable. The utility model places the plug-in core sleeve below, and the shell above. Although the welding gun is inverted, the plug-in core sleeve is below, which solves the difficulty of poor concentricity adjustment under the premise of not affecting the welding process, and also realizes the process of automatic direction recognition and automatic protective cap removal, and the yield is guaranteed to 100%.
