A limit plate 22 is provided on one side of the box body 11, and a detection end of the pressure sensor 68 is provided on the limit plate 22 near the box body 11. Before the cover closing device 5 is activated, the plug 61 is arranged on the box body 11. After the cover closing device 5 is activated, the plug 61 is sandwiched between the box body 11 and the box cover 12. The pulling driver 62 is transmission-connected to the plug 61 , and the pulling driver 62 is used to pull the plug 61 in the direction from the box body 11 to the limiting plate 22 .

[0019] Based on the above device, the principle is that the injection molded product 1 is placed on the fixing frame 2, the box body 11 is received in the limiting groove 210, and the limiting groove 210 is used to position the injection molded product 1. Before the cover closing device 5 is started, the box body 11 and the box cover 12 are in an open state. After the cover closing device 5 is started, the plug 61 is clamped between the box body 11 and the box cover 12. The plug 61 is pulled by the pulling driver 62. Due to the limitation of the limiting plate 22, the box body 11 will not move. The pressure generated by the box body 11 in this process is detected by the pressure sensor 68 to determine whether the box body 11 and the box cover 12 are tightly pressed. If the pressure sensor 68 detects that the pressure is greater than the preset value, it is judged that the box body 11 and the box cover 12 are tightly pressed and the product is qualified. If the pressure sensor 68 detects that the pressure is less than the preset value, it is judged that the product is unqualified. In this embodiment, the thickness of the plug 61 is 0.2 mm. The fixing frame 2 includes a horizontal plate 21, and the limiting groove 210 is set on the horizontal plate 21.

[0020] Combination Figure 4 As shown, in this embodiment, the cover closing device 5 includes a third driving assembly 52 and a swing frame 51 rotatably mounted on the fixed frame 2.

At this time, the plug 61 at the front section is cut off, and the unworn plug 61 at the rear section is connected to the limit plate 22. In addition, before the pulling driver 62 is started, the winding shaft driver 66 locks the winding shaft 64 to prevent the winding shaft 64 from rotating; in the process of the pulling driver 62 pulling the plug 61, the winding shaft driver 66 is in an unlocked state, and the winding shaft 64 rotates in the R direction as the plug 61 is pulled; when the plug 61 is reset, the winding shaft driver 66 drives the winding shaft 64 to rotate to pull the sliding seat 622 to reset, and the pulling drive cylinder 621 is in an invalid state during this process. In this embodiment, the winding shaft driver 66 is a stepping motor, and the winding shaft driver 66 and the winding shaft 64 are connected by a synchronous pulley-synchronous belt transmission. In other embodiments, a tension controller may be provided on the winding shaft 64 to prevent the winding shaft 64 from rotating too far when the plug 61 rotates. The specific tension controller may be a coil spring (not shown), which is provided between the winding shaft 64 and the flip frame 63 and is used to apply an elastic force opposite to the R direction to the winding shaft 64 to ensure synchronization when the winding shaft 64 is pulled and rotated.

[0027] In this embodiment, a positioning roller 67 is provided on the flip frame 63. When the flip frame 63 is in the first posture, the positioning roller 67 is arranged on the side of the box body 11 away from the limiting plate 22.

[0029] That is, a pair of vertically arranged connecting plates 632 are slidably connected to the sliding seat 622 to ensure the stability of the connection between the sliding seat 622 and the turning frame 63 during the turning and switching of the turning frame 63. Specifically, when the turning frame 63 is in the first posture, one of the connecting plates 632 is below the sliding seat 622.

[0030] In this embodiment, the box cover 12 is provided with a cover opening slot 1211; Figure 6As shown, the cover opening device 7 is also included, and the cover opening device 7 includes a cover opening driver, a transmission frame 72 and a push frame 73.
