Hereinafter, the operation of this embodiment will be specifically described. Referring to FIG. 1 , FIG. 3 to FIG. 9 , in this embodiment, the carrier unit 7 is two examples. In the following, for the convenience of description and to simplify the description content, the carrier units 7 are exemplified by the first carrier unit 7a and the second carrier unit 7b. When the first carrier unit 7a is transferred to the top carriers 22 by an external device (not shown), as shown in FIG. 3 , at this time, the movable carriers 323 are at the position to be picked up, and the The clamping device 45 is in the waiting position, and the opening and closing elements 451 are in the open state. Then, the lifting cylinder 311 of the lifting device 31 operates, so that the translation devices 32 are driven by the first linking member 314 (see FIG. 2 ) to move upward, and the movable stages 323 follow the loop path X (See Fig. 5) Move from the to-be-reclaimed position to the already-reclaimed position, as shown in Fig. 4, instead, the movable platforms 323 support the first carrier unit 7a, so that the first carrier unit 7a Transfer to the conveyor system 3 . Then, the translation cylinders 321 of the translation device 32 operate, so that the movable stages 323 are driven by the second linking members 324 to move forward, and the movable stages 323 move along the loop The path X moves from the reclaimed position to the intermediate process position, as shown in FIG. 5 . At this time, the movable carriers 323 continue to support the first carrier unit 7a, so that the first carrier unit 7a follows the The transport system 3 is transferred above the bottom stages 46 . Then, the lifting cylinder 311 of the lifting device 31 operates, so that the translation devices 32 are driven by the first linkage 314 to move downward, and the movable stages 323 follow the loop path X (see FIG. 5 ). ) from the intermediate process position to the material loading position, as shown in FIG. 6 , the first carrier unit 7a is supported by the bottom carriers 46 instead, so that the first carrier unit 7a is transferred to the opening unit 4.

Continuing the above steps, when the first carrier unit 7a is transferred to the clip opening unit 4, and the movable platforms 323 are located at the material placement position, the pulling device 44 operates to drive the clip devices 45 from The waiting position is moved to the opening position. As shown in FIG. 7 , the clamping devices 45 are in the opening position, and the opening and closing elements 451 are in the open state. Then, the clamping devices 45 operate respectively to drive the opening and closing elements 451 of each of the clamping devices 45 to switch from the open state to the closed state. As shown in FIG. 8 , the clamping devices 45 In the opening position, the opening and closing elements 451 are close to each other and exert force on the clamps 72 , so that the clamps 72 clamp the plate 8 . Finally, the clamping devices 45 operate respectively, so that the opening and closing elements 451 of each clamping device 45 are switched from the closed state to the open state, and at the same time, the pulling device 44 operates to drive the clamping devices The latching device 45 moves from the opening position to the waiting position. So far, the operation steps of transferring the first carrier unit 7a to the corresponding board member 8 and clamping the board member 8 by the first carrier unit 7a are completed. Subsequently, the translation cylinders 321 operate, so that the movable stages 323 are driven by the second linking members 324 to move backward respectively, and the lift cylinder 311 operates successively, so that the movable stages 323 are driven by the first link 324. The linking member 314 (see FIG. 2 ) is driven to move upward, and moves the movable stages 323 along the loop path X (see FIG. 5 ) from the material-receiving position to the to-be-reclaimed position, in addition to , the second carrier unit 7b is transferred to the top carriers 22 by external equipment. As shown in FIG. 9 , the movable carriers 323 are ready to transfer the second carrier unit 7b at the position to be picked up. The clamping device 45 is in the waiting position, and the first carrier unit 7a is loaded with the plate 8 . So far, the entire operation process along the loop path X is completed. At this time, the first carrier unit 7a holding the plate 8 can be transferred by other external equipment (not shown) for subsequent processing procedures. The second carrier unit 7b can start the operation process of transferring, clamping and the like of the first carrier unit 7a as described above. In this way, as shown in FIG. 5 , the loop path X represented by the running track of the movable stage 22 on the right side runs counterclockwise in the drawing.

In other embodiments, when the movable carriers 323 move from the intermediate process position to the material placement position, the first carrier unit 7 a is transferred to the clip opening unit 4 . Next, the clamping devices 45 are moved between the waiting position and the clamping opening position, and the clamping procedure of the first carrier unit 7a is performed. At this time, the movable carriers 323 can follow the loop The path X moves from the loading position through the to-be-reclaimed position and the already-reclaimed position in sequence to the intermediate process position, so that the second carrier unit 7b is transferred from the top carriers 22 to the movable carriers 323 and above the bottom stages 46 . In this way, when the first carrier unit 7a is removed by another external device (not shown), the movable stages 323 can follow the loop path X to move to the material placement position, so that the movable stages 323 The time for detouring the loop path X is shortened, and the transfer efficiency is improved.

It is worth mentioning that, in other embodiments, the bottom carriers 46 of the clip opening unit 4 can be omitted. Except for the stage 22 to support the first carrier unit 7a, the movable stages 323 are used to support the first carrier unit 7a during other operations. More specifically, the movable stages 323 are sequentially cyclically moved along the loop path X including the position to be retrieved, the position that has been retrieved, and the position to be placed as described above. During the process of moving the movable stages 323 from the reclaimed position to the material placement position along the loop path X, the translation cylinders 321 operate first, so that the movable stages 323 support the first load The tool unit 7a is driven by the second linking members 324 to move forward, so that the movable carriers 323 are not aligned with the top carriers 22, and then the lift cylinder 311 operates to make the movable carriers 323 move forward. The stage 323 supports the first carrier unit 7a, and is driven by the first linking member 314 to move downward. In this way, when the movable carriers 323 are located at the material placement position, since the bottom carriers 46 are omitted, the movable carriers 323 are adjacent to the plate 8 and still support the first carrier unit 7a. At this time, the first carrier unit 7a is in the state supported by the movable platforms 323 to perform the clamping procedure, and similarly the clamping devices 45 can be between the waiting position and the clamping position. Moving, and at the opening position, the clamping devices 45 can perform the opening procedure for the first carrier unit 7a loaded on the movable stages 323 . When the opening procedure is completed and the first carrier unit 7a is removed by another external device, the movable carriers 323 can also be moved along the loop path X from the loading position to the waiting position to prepare The second carrier unit 7b is transferred, in this way, the purpose of transferring the carrier to the position to be loaded with the board 8 and loading the board 8 on the carrier unit 7 in an automated manner can also be achieved.

Referring to FIG. 10 , it is another implementation aspect of the embodiment. This embodiment is similar in structure to the above-mentioned embodiment of FIGS. 1 to 9 . The main difference is that, in this embodiment, the temporary storage unit 2 is suitable for being installed on an external bearing structure 9 , the external bearing structure 9 includes an external supporting surface 91 facing the support base 1 , the first bracket 21 is connected to the external support surface 91 , and the top stages 22 of the temporary storage unit 2 are respectively connected to the left and right opposite sides of the first bracket 21 and away from the external support surface 91 . More specifically, in this embodiment, the outer support structure 9 and the support base 1 are spaced back and forth from each other, so that the top stages 22 are located between the outer support structure 9 and the support base 1, and the The distance of the top stage 22 relative to the support base 1 is greater than the distance of the bottom stages 46 relative to the support base 1 . In this way, when the movable stages 323 are sequentially moved cyclically in the loop path X including the position to be picked up, the position that has been picked up, the intermediate process position and the loading position, the movable stages 323 are relatively opposite to each other. The positions of the top stages 22 and the bottom stages 46 have not changed. However, when the positions of the top stages 22 relative to the bottom stages 46 are changed such that the movable stages 323 are moved along the loop path X from the reclaimed position to the intermediate process position, the The movable stage 323 is driven by the second linkage members 324 to move backward. In addition, when the movable stages 323 move from the material placement position to the to-be-reclaimed position along the loop path X, the movable stages 323 are first driven by the second linkage members 324 to move forward. Then, the movable stages 323 are driven by the first linking member 314 to move upward. In this way, as shown in FIG. 10 , the loop path X represented by the running track of the movable stage 22 on the right side runs clockwise in the drawing.

To sum up, as the guide rod 43 is driven by the pulling device 44 to move, the clamping device 45 can be driven to move between the material-waiting position and the clamping-opening position, so that the clamping device 45 is adjacent and The fixture 72 is aligned, and the clamping procedure of the fixture 72 is performed to achieve the purpose of loading the circuit board on the carrier in an automated manner. In addition, the movable stages 323 can move cyclically on the loop path X in sequence, so that the carrier unit 7 is transferred from being loaded on the top stages 22 to being loaded on the movable stages 323, and along with the When the movable carrier 323 moves to the material placement position, the purpose of automatically transferring the carrier to the position where the circuit board is to be loaded can be achieved. In addition, because the movable stages 323 can move cyclically on the loop path X in sequence, the carrier unit 7 can be transferred from the top stage 22 to the top stage 22 along with the movable stages 323 The bottom stage 46, and when the clamping device 45 performs the clamping procedure of the clamp 72 on the carrier unit 7 loaded on the bottom stage 46, the movable stages 323 continue to follow the loop path X moves to the to-be-reclaimed position for the next round of transferring another carrier unit 7, which can omit the need for the movable carriers 323 to wait for the clamping device 45 to perform the clamping procedure when the loop path X moves. Therefore, the purpose of the present invention can be achieved indeed.

However, the above are only examples of the present invention, and should not limit the scope of implementation of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the patent specification are still included in the scope of the present invention. within the scope of the invention patent.
