The number of the moving blocks 31 is two and they are respectively arranged on the left and right sides of the top of the placement shell 23. The bottom of the moving block 31 on the top of the slider 25 is fixedly connected. The side of the moving block 31 close to the placement shell 23 is in sliding contact with the placement shell 23. A rotating shaft 32 is movably connected in the groove at the top of the moving block 31 through a bearing. The top of the rotating shaft 32 is fixedly connected to an adjustment plate 33. The bottom of the adjustment plate 33 is in rotational contact with the top of the moving block 31. The left and right sides of the adjustment plate 33 are fixedly connected to connecting blocks 34. The two connecting blocks 34 are respectively fixedly connected to an arc-shaped clamping block 35 and a square clamping block 36. The two moving blocks 34 are located on the same side. A connecting groove 37 is provided on the side away from each other of the movable block 31, and the top and bottom of the inner wall of the connecting groove 37 are fixedly connected by a fixing rod 38. A pull plate 39 is slidably connected to the surface of the fixing rod 38. The side of the pull plate 39 away from the rotating shaft 32 passes through the connecting groove 37 and extends to the outside thereof. An elastic member 310 is sleeved on the surface of the fixing rod 38. The elastic member 310 is made of a spring. A clamping block 311 is fixedly connected to the top of the pull plate 39. Adjusting blocks 312 are fixedly connected to the bottoms of the left and right sides of the movable block 31.

The top of the clamping block 311 passes through the connecting groove 37 and the clamping groove 313 from bottom to top in sequence and extends to the inside of the clamping groove 313 and contacts with the inner wall of the clamping groove 313.

[0028] Specifically, an arc-shaped clamp 35 or a square clamp 36 is selected according to the shape of the charger shell. When the arc-shaped clamp 35 is needed, the pull plate 39 is pulled downward, and the pull plate 39 squeezes the elastic member 310 to move. The pull plate 39 drives the clamping block 311 to move downward, so that the clamping block 311 and the clamping slot 313 are separated. Then the adjustment plate 33 is rotated, and the adjustment plate 33 drives the rotating shaft 32 to rotate 180 degrees. The adjustment plate 33 drives the adjustment block 312 to rotate, so that the arc-shaped clamp 35 and the square clamp 36 exchange positions. Then the pull plate 39 is released, and the elastic member 310 drives the pull plate 39 to move upward through the restoring elastic force of the elastic member 310, and the pull plate 39 drives the clamping block 311 to be inserted into another clamping slot 313.

[0029] Through the cooperation of the servo motor 21, the annular plate 22, the placement shell 23, the electric push rod 24, the slider 25, the moving block 31, the rotating shaft 32, the adjusting plate 33, the connecting block 34, the arc clamping block 35, the square clamping block 36, the connecting groove 37, the fixing rod 38, the pulling plate 39, the elastic member 310, the clamping block 311, the adjusting block 312 and the clamping groove 313, the efficiency of pressing the PCBA into the charger housing is improved, and the need to remove the charger from the fixture before pressing the next charger after the pressing is completed is avoided. In addition, the arc clamping block 35 and the square clamping block 36 can be selected as needed to facilitate the clamping and fixing of round and square chargers, thereby improving the flexibility and applicability during use.

[0030] When in use, place the charger shell on the placement shell 23, and then start the electric push rod 24. The electric push rod 24 drives the moving block 31 to move through the slider 25. The moving block 31 drives the square clamp block 36 to move close to the charger shell, so that the square clamp block 36 clamps and fixes the charger shell. Then place the PCBA on the charger shell, and then start the cylinder 12. The cylinder 12 drives the pressure rod 14 to move downward through the movable block 13, so that the PCBA can be pressed into the inside of the charger shell. After the pressing is completed, the cylinder 12 drives the pressure rod 14 to move upward, and then start the servo motor 21. The servo motor 21 drives the annular plate 22 to rotate 180 degrees through the output shaft, so that the charger shell to be pressed on the right side moves to the left side, and the charger shell after pressing is completed moves to the right side. The pressure rod 14 continues to press, and the charger shell on the right side after pressing is removed.
