When in use, the valve body 3 is placed In the support frame 6, start the chain plate conveyor belt 2, the chain plate conveyor belt 2 will drive the valve body 3 to move horizontally, the feeding mechanism will convey the top cover body 4 to the top of the valve body 3, the limiting mechanism will block the top cover body 4, so that the valve body 3 is in contact with the top cover body 4, and when the valve body 3 and the top cover body 4 are conveyed to the correction component together, the correction component aligns the top cover body 4 and the valve body 3, so that the threaded holes of the top cover body 4 and the valve body 3 are aligned, which is convenient for installing the screws, and at the same time can support the valve body 3, so that when the valve body 3 and the top cover body 4 are assembled, the valve body 3 will not rotate, thereby improving the assembly efficiency of the solenoid valve.

[0024] In order to improve the loading efficiency of the top cover body 4, the loading assembly in the present invention includes a second fixing frame 20, and the second fixing frame 20 is fixed to the outer wall of one side at one end of the top of the frame body 1 by bolts, and the top ends of the inner walls on both sides of the second fixing frame 20 are fixed with support rods 21 by bolts, and multiple top cover bodies 4 are located in the support rods 21, and the support rods 21 have a certain inclination angle, and one side of the second fixing frame 20 is provided with a blocking mechanism for limiting the top cover body 4, and multiple top cover bodies 4 are placed between two support rods 21. The inclined support rods 21 will cause the top cover body 4 to slide downward, releasing the limiting mechanism on the bottom top cover body 4, so that the top cover body 4 can fall on the valve body 3, and the top cover body 4 can fall on the valve body 3 without manual installation, thereby reducing the workload of workers and further improving the assembly efficiency of the solenoid valve.

[0025] In order to detach only one top cover body 4 at a time, the blocking mechanism includes two fixing rods 25, which are respectively welded to the inner walls on both sides of the second fixing frame 20, and a rotating shaft 29 is rotatably connected between the inner walls on both sides of the two fixing rods 25. A rotating frame 27 is welded to the circumferential outer wall of the rotating shaft 29, and the rotating frame 27 can contact the top cover body 4 located at the bottom between the two sides of the support rod 21. Two symmetrically distributed fixing columns 28 are fixed to the bottom of the rotating frame 27 by bolts. One side of the two fixing rods 25 is provided with a restoring component for rotating the rotating frame 27 clockwise. Pulling one end of the fixing column 28 so that the fixing column 28 and the rotating frame 27 rotate synchronously will cause the rotating frame 27 to be out of contact with the top cover body 4. Under the action of gravity, The top cover body 4 falls on the valve body 3 and is blocked by the limit mechanism. The restoration component will drive the rotating frame 27 to reset, thereby blocking the top cover body 4 at the rear, and then achieving the goal of only one top cover body 4 falling at a time, which can make the top cover body 4 just fall on the valve body 3, and prevent the top cover body 4 from falling onto the chain conveyor belt 2, thereby improving the conveying accuracy of the device. The restoration component includes a torsion spring 26, which is fixed to one end of the outer wall of one side of the fixed rod 25 by bolts, and both ends of the rotating shaft 29 pass through the fixed rod 25 and are fixed to the torsion spring 26. The rotation of the rotating frame 27 will cause the torsion spring 26 to deform and generate torque. When the rotating frame 27 loses the force to drive the rotating frame 27 to rotate, the torsion spring 26 will drive the rotating frame 27 to rotate in the opposite direction, thereby resetting the rotating frame 27.

[0026] In order to limit the position of the top cover body 4, the limiting mechanism includes a first fixing frame 19, which is fixed to one side of one end of the top of the frame body 1 by bolts, and a connecting plate 22 is welded to one end of the first fixing frame 19, and a plurality of symmetrically distributed springs 23 are fixed to one side of the connecting plate 22 by bolts, and a contact plate 24 is welded to the other end of the spring 23, and the contact plate 24 is in contact with one of the top cover bodies 4. The spring 23 can buffer the fallen top cover body 4 to avoid excessive impact force when the top cover body 4 falls directly and cause damage to the top cover body 4. When the top cover body 4 detaches from the support rod 21, the top cover body 4 will contact the contact plate 24, thereby blocking and limiting the top cover body 4, so that the top cover body 4 just falls on the valve body 3, further improving the accuracy of the top cover body 4 falling into position.

[0027] In order to align the threaded holes of the top cover body 4 with the valve body 3, the correction assembly includes two fixing plates 10, and the two fixing plates 10 are respectively fixed to the outer walls of both sides of the support frame 6 by bolts. The two fixing plates 10 are both L-shaped, and the tops of the two fixing plates 10 are provided with slide grooves 11, and slide rods 13 are slidably connected in the slide grooves 11. The top of the slide rod 13 is fixed with a clamping frame 14 by bolts, and a groove 15 is provided on one side of the clamping frame 14, and part of the valve body 3 and the top cover body 4 are located in the groove 15. One side of the inner wall of the two fixing plates 10 is provided with an elastic component for pulling the slide rod 13 to reset. Two symmetrically distributed extrusion frames 5 are fixed to the top of the frame 1 by bolts, and both ends of the extrusion frame 5 are arc surfaces 18. When the chain plate conveyor belt 2 drives the top cover body 4 and the valve body 3 to move, the slide rod 13 and the arc surface 18 are caused to align. The top cover body 4 is in contact with the surface 18, thereby squeezing the slide bar 13 and the clamping frame 14 to move toward the middle, and then the groove 15 squeezes the top cover body 4, so that the position of the top cover body 4 is changed, so that the top cover body 4 is aligned with the threaded hole of the valve body 3, thereby facilitating the assembly of the top cover body 4 and the valve body 3, without the need for manual auxiliary alignment, thereby improving the labor-saving effect of the device, the elastic component is a tension spring 12, the tension spring 12 is fixed to one side of the slide bar 13 by bolts, and the other end of the tension spring 12 is fixed to the fixed plate 10, and the bottom of one side of multiple clamping frames 14 on the same side is provided with an inclined surface 9. During the movement of the clamping frame 14, the inclined surface 9 on one side of the clamping frame 14 can squeeze one end of the fixed column 28, so that the fixed column 28 and the rotating frame 27 rotate at the same time, without the need to manually rotate the fixed column 28, further improving the labor-saving effect of the device.

[0028] Among them, placement grooves 7 matching the valve body 3 are opened on the top of both sides of the support frame 6, and limiting grooves 8 for auxiliary positioning of the valve body 3 are opened on the bottom inner wall of the support frame 6. Rubber pads 16 are bonded to the bottom inner wall of the support frame 6. The rubber pads 16 protect the valve body 3 to prevent the valve body 3 from being damaged by being placed directly on the support frame 6. A baffle 17 is fixed to the outer wall of one side of the support frame 6 by bolts to assist in limiting the valve body 3 and improve the placement efficiency of the valve body 3.

[0029] Working principle of the present invention: when in use, the valve body 3 is placed in the support frame 6, and multiple top cover bodies 4 are placed between two support rods 21. The inclined support rods 21 will make the top cover bodies 4 slide downward. Under the action of gravity, the bottom top cover body 4 will contact the contact plate 24, blocking and limiting the top cover body 4 so that the top cover body 4 just falls on the valve body 3. The chain plate conveyor belt 2 is started, and the chain plate conveyor belt 2 will drive the valve body 3 to move horizontally. When the clamping frame 14 is out of contact with the fixed column 28, the deformed torsion spring 26 with torsion will drive the rotating frame 27 to rotate, so that the rotating frame 27 is reset, thereby blocking the remaining top cover bodies 4. When the inclined surface 9 contacts the fixed column 28, the inclined surface 9 will squeeze the fixed column 28. The top cover body 4 is moved downwards by the chain conveyor belt 2, and the sliding rod 13 is brought into contact with the arc surface 18, thereby squeezing the sliding rod 13 and the clamping frame 14 to move toward the middle, and then the groove 15 squeezes the top cover body 4, so that the position of the top cover body 4 is changed, so that the threaded holes of the top cover body 4 and the valve body 3 are aligned, thereby facilitating the assembly of the top cover body 4 and the valve body 3 without manual auxiliary alignment. At the same time, the valve body 3 can be supported so that when the valve body 3 and the top cover body 4 are assembled, the valve body 3 will not rotate, thereby improving the assembly efficiency of the solenoid valve.
