Description

Technical Field

[0001] The utility model relates to the field of gas solenoid valves, in particular to an automatic coil tinning device. Background Technique

[0002] During the production of gas solenoid valves, the enameled wire of the gas solenoid valve coil is welded to the skeleton terminals at the incoming and outgoing lines. The currently used welding method is to manually place the wound coil into the tin pot for tinning at one time. Since the length of the skeleton exposed after winding the enameled wire on the skeleton terminal is less than 1 mm, and the skeleton is made of plastic, the tinning error tolerance is very small. Improper operation by workers is likely to cause situations such as dry soldering, over soldering, and damaging the skeleton, resulting in low production efficiency and large production losses.

[0034] The suction cup mechanism 4 is installed on the Z-axis slider of the XYZ transfer mechanism 5 through the connecting plate 43, and is used to pick up and put down the mold 6. The structure of the suction cup mechanism 4 is as shown in Figure 7 Figure [not provided], and includes a suction nozzle 41, an infrastructure 42, and a connecting plate 43. The infrastructure 42 is built by three aluminum profiles. Among them, two aluminum profiles are parallel, and the two sides of the third aluminum profile are respectively vertically connected to the above two parallel aluminum profiles through aluminum profile corner right connectors 45. By changing the connection position of the aluminum profile corner right connectors 45, the distance between the two parallel aluminum profiles can be controlled, so as to adjust the horizontal position between the suction nozzles; the suction nozzle 41 is installed on the sides of the two parallel aluminum profiles through the mounting plate 44. By changing the position of the mounting plate 44, the front and back positions of the suction nozzle 41 can be adjusted, so as to stably contact the mold surface. Under the action of the pneumatic device, the mold surface is picked up or put down;

[0035] The structure of the XYZ transfer mechanism 5 is as shown in Figure 8 Figure [not provided], and includes an X-axis slide rail 51, a Z-axis slider 52, a Z-axis slide rail 53, a Y-axis slide rail 54, a Y-axis slider 55, and an X-axis slider 56.

Motors are provided in the X, Y, and Z directions. The motors drive the lead screws to rotate, thereby driving the sliders in the three directions to move in each direction. Several sensors are installed on the side, which can sense the position of the sliders; drag chains are installed on the X-axis and Y-axis. The drag chains drive the wires of the relevant electrical components to move with the movement of the X-axis and Y-axis sliders, avoiding the damage to the wires caused by moving friction.

[0037] The mold is used to place the coil assembly. The surface of the mold is smooth. Its structure is as shown in Figure 9As shown in the figure, it includes a chassis 61, magnet blocks 62, and an upper pressing cover 63. There are 24 holes for placing coil components on the chassis 61, with through-holes below the holes to pass through the solder joints of the coil components 64. After the coil components 64 are placed in the holes, their solder joints will protrude about 2 mm from the lower surface through the through-holes to stably contact the tin liquid for successful soldering. Magnet blocks 62 are provided on both the left and right sides of the surface of the mold 6, and magnet blocks 62 are also provided on both the left and right sides of the upper pressing cover 63. After the coil components 64 are placed, the upper pressing cover 63 is placed on top. An iron sheet that conforms to the surface curve of the coil components 64 is installed inside the upper pressing cover 63. The magnets at both ends of the upper pressing cover 63 are attached to the magnet blocks 62 below, which can limit the displacement of the coil components 64 in the up and down directions and stabilize the coil components 64 in the holes. There is an arrow symbol in the upper left corner of the surface of the mold, and an arrow symbol in the upper left corner of the upper pressing plate, which is convenient for keeping the correct direction when placing the upper pressing plate.

[0038] The specific operation process is as follows:

[0039] (1) At the manual operation position, 24 coil components 64 are placed in the holes of the mold 6, and the upper pressing cover 63 is covered. The arrow symbol on the upper pressing cover 63 should be consistent with the arrow symbol on the surface of the mold 6. The upper pressing cover 63 is attracted to the magnet block 62 below, and the fixation of the coil components 64 is completed. Then, the entire mold 6 is placed on the feeding conveyor belt 11. There is a stop block on the feeding conveyor belt 11, and the mold 6 stops here, which is the suction position.

[0040] (2) After the mold 6 is transported to the suction position, the XYZ transmission mechanism 5 drives the suction cup mechanism 4 to the suction position. The suction cup structure 4 moves down until the bottom of the suction nozzle 41 touches the surface of the mold 6. After the pneumatic device acts, the suction nozzle 41 adsorbs the upper mold 6 and moves up.

[0041] (3) The XYZ transmission mechanism 5 transports the mold 6 to the tinning position. The mold 6 moves down until the lower surface of the mold touches the tin liquid and stabilizes for 2 s to complete the tinning process.

[0042] (4) After tinning, the mold 6 moves up. The XYZ transmission mechanism 5 transports the mold 6 to the placement position. The mold 6 moves down and is placed on the output conveyor belt 12. At the same time, the pneumatic device acts, the suction nozzle 41 releases, and the mold 6 separates from the suction nozzle 41 and is sent out through the output conveyor belt 12. There is a stop block at the manual position on the output conveyor belt 12, and the mold 6 stops here.

[0043] (5) At this time, the tin scraping device of the tinning device 2 works. The slider movement of the mechanical rodless cylinder 22 drives the tin scraping blade 26 to work from front to back to scrape the tin slag on the surface of the tin surface to the rear slag collection area.

[0044] (6) After the mold 6 reaches the manual position, the operator removes the mold 6 from the conveyor belt and removes the upper pressing plate on the mold to obtain the coil components 64 after tinning.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
