The moving contact piece mounting structure 103 is used to place the moving contact piece on the mounting plate 169, and the installation piece mounting structure 105 is used to place the installation piece on the mounting plate 169.

[0049] Reference Figure 8 The mounting plate moving assembly 149 includes a mounting plate placement pipe 154 and a mounting plate driving component 155. The mounting plate driving component 155 includes a moving cylinder 172 and a moving plate 173. The moving cylinder 172 is fixedly connected to the support frame 148, and the moving plate 173 is fixedly connected to the driving shaft of the moving cylinder 172.

[0050] Reference Figure 7 and Figure 8The mounting plate placement pipe 154 is fixedly connected to the stationary contact piece mounting structure 104 and the mounting piece mounting structure 105, and the mounting plate 169 is placed in the mounting plate placement pipe 154. There is a gap between the mounting plate placement pipe 154 and the surface of the support frame 148, and the gap is only for a single mounting plate 169 to pass through, and the movable plate 173 can be located between the mounting plate placement pipe 154 and the support frame 148.

[0051] Reference Figure 8 When the moving cylinder 172 is started, the moving cylinder 172 pushes the moving plate 173, and the moving plate 173 drives the mounting plate 169 to leave the gap between the mounting plate placement pipe 154 and the support frame 148. At this time, the moving plate 173 is located in the gap between the mounting plate placement pipe 154 and the support frame 148, making it difficult for the mounting plate 169 to continue to fall from the mounting plate placement pipe 154.

[0052] Reference Fig. 9 and Fig.10 A movable groove 156 is provided on the surface of the mounting plate 169, and the movable groove 156 extends in the vertical direction. A movable bar 157 is fixedly connected on the surface of the movable plate 173, and the movable bar 157 can be inserted into the movable groove 156. A groove 158 is provided on the groove wall of the movable groove 156, and a retaining spring 159 is fixedly connected to the bottom wall of the groove 158. A second magnet 160 is fixedly connected to the surface of the retaining spring 159 away from the bottom wall of the groove 158, and a retaining bar 161 is fixedly connected to the surface of the second magnet 160 away from the retaining spring 159.

[0053] Reference Fig.10 A stopper hole 162 is provided on the surface of the moving bar 157, and the stopper hole 162 is for the stopper bar 161 to be inserted. The stopper spring 159 drives the stopper bar 161 to be inserted into the stopper hole 162, and at this time, the stopper bar 161 abuts against the groove wall of the moving groove 156. When the stopper bar 161 abuts against the groove wall of the moving groove 156, the stopper spring 159 is in a non-stressed state; when the stopper bar 161 does not abut against the groove wall of the moving groove 156, the stopper spring 159 is in a compressed state.

[0054] Reference Fig.10 A stop bevel 163 is provided on the side of the stop bar 161 facing the opening of the moving groove 156 , and the distance between the stop bevel 163 and the moving plate 173 gradually decreases along the direction from the stop bar 161 to the stop spring 159 , and the stop bevel 163 is located on the insertion path of the moving bar 157 .

[0055] Reference Figure 8 and Fig.10When the moving cylinder 172 is started, the moving cylinder 172 pushes the moving plate 173, allowing the moving bar 157 to be inserted into the moving groove 156. At this time, the moving bar 157 pushes the stop bar 161 to move through the stop slope 163, allowing the stop bar 161 to be inserted into the stop hole 162. At this time, the stop bar 161 and the moving bar 157 are fixed to each other until the mounting plate 169 moves to the through hole 151, and a part of the mounting plate 169 falls. Since the moving groove 156 extends in the vertical direction, the moving bar 157 is still located in the moving groove 156.

[0056] Reference Figure 8 and Fig.10 The mounting plate mounting assembly 147 includes a mounting claw 170 and a movable assembly 171. The mounting claw 170 is fixedly connected with a first magnet 164, and the first magnet 164 can absorb the second magnet 160. When the mounting claw 170 grabs the mounting plate 169, the first magnet 164 absorbs the second magnet 160, so that the second magnet 160 drives the stop bar 161 to move toward the direction of the stop spring 159, so that the stop bar 161 is separated from the stop hole 162, and the moving bar 157 can be separated from the moving groove 156. At this time, the installation package can fall smoothly from the through hole 151.

[0057] Reference Figure 7 and Figure 8 The movable component 171 is used to move and install the mechanical claw 170. The structure of the movable component 171 is the same as that of the suction moving component 138, and is also composed of a horizontal cylinder 140 and a longitudinal cylinder 141.

[0058] Reference Figure 8 The movable component 171 drives the installation mechanical claw 170 to move onto the installation plate 169, allowing the first magnet 164 to absorb the second magnet 160, so that the installation plate 169 can fall from the through hole 151, and the movable component 171 drives the installation mechanical claw 170 to move onto the shell. At this time, the static contact piece and the installation piece are both located in the installation groove. The movable component 171 drives the installation plate 169 to move through the installation mechanical claw 170, allowing the static contact piece and the installation piece to fall from the installation plate 169 to the shell.

[0059] Reference Figure 8 and Fig.10 The mounting plate unloading assembly 150 includes an unloading conveyor belt 165, a first magnetic attraction groove 166 is provided on the surface of the unloading conveyor belt 165, a third magnet 167 is fixedly connected in the first magnetic attraction groove 166, and the third magnet 167 extends along the length direction of the unloading conveyor belt 165. A second magnetic attraction groove 168 is provided on the surface of the mounting plate 169, and an iron sheet 146 is fixedly connected in the second magnetic attraction groove 168.

[0060] Reference Figure 8 and Fig.10When the movable component 171 drives the mounting plate 169 to move into the unloading conveyor belt 165 , the third magnet 167 attracts the iron sheet 146 , so that the mounting plate 169 can be fixed in the unloading conveyor belt 165 , thereby preventing the mounting plate 169 from being separated from the unloading conveyor belt 165 .

[0061] The implementation principle of Example 2 is as follows: the moving cylinder 172 drives the moving plate 173 to push the mounting plate 169 to move to the through hole 151. At this time, the moving bar 157 is inserted into the moving groove 156, and the stop bar 161 is inserted into the stop hole 162, so that the mounting plate 169 will not fall from the through hole 151. Then the movable component 171 drives the installation mechanical claw 170 to grab the mounting plate 169. At this time, the first magnet 164 absorbs the second magnet 160, so that the second magnet 160 drives the stop bar 161 to disengage from the stop hole 162, and the moving cylinder 172 drives the moving bar 157 to disengage from the moving groove 156. At this time, the mounting plate 169 can pass through the through-hole 151, and the movable component 171 drives the mounting plate 169 to move onto the shell, so that the static contact piece and the mounting piece are placed on the shell, and the movable component 171 drives the mounting plate 169 to move, so that the static contact piece and the mounting piece are separated from the mounting plate 169 from the side through which the accommodating groove 152 passes, so that the static contact piece and the mounting piece can be located on the shell, and finally the movable component 171 drives the mounting plate 169 to move to the unloading conveyor belt 165 by installing the mechanical claw 170. At this time, the third magnet 167 attracts the iron sheet 146, so that the unloading conveyor belt 165 drives the mounting plate 169 to move.
