An embodiment of the present application provides a transfer mechanism for package loading, as shown in fig. 1 and 2, for transporting a cartridge 2 and loading the cartridge 2 onto a cartridge placement site of a packaging apparatus. The transfer mechanism includes an endless conveyor belt, a lifting bar 41, and the like.

Specifically, the outer surface array of the band body of annular conveyer belt is equipped with a plurality of pairs of telescopic links 1, and every telescopic link 1 top all is equipped with roof 11, roof 11 be used for bearing magazine 2 and with magazine 2 bottom recess block cooperation when bearing.

The jacking strips 41 are arranged horizontally at intervals and are arranged on two sides above the horizontal section belt body of the annular conveying belt and are arranged in a moving mode along the vertical direction perpendicular to the horizontal section belt body, and specifically, the jacking strips 41 are connected to the moving end of the vertical cylinder 4 so as to realize lifting movement along the vertical direction.

The material box is placed above the horizontal section belt body and comprises a pair of concave plates 3 which are arranged at intervals on two sides of the horizontal section belt body and a pair of symmetrically arranged L-shaped clamping plates 31 which are matched in the concave plates 3, the horizontal section of the L-shaped clamping plates 31 is in sliding fit in a sliding groove of the horizontal section of the concave plates 3, and the vertical section of the L-shaped clamping plates 31 is connected with the vertical section of the concave plates 3 through springs, wherein the upper ends of the vertical sections of the L-shaped clamping plates 31 can be inclined outwards so as to form a guide opening and matched with springs so as to facilitate the falling and stabilization of the material box 2.

The jacking strip 41 is located between the concave plate 3 and the horizontal section belt body, and the length of the top plate 11 is larger than the width of the horizontal section belt body, and the length of the jacking strip 41 is set so as to be capable of at least covering two adjacent top plates 11. When the top end of the vertical section of the L-shaped clamping plate 31 is higher than the bottom of the material box 2 borne by the top plate 11 on the horizontal section belt body by a predetermined distance, the requirement that the top end of the vertical section of the L-shaped clamping plate 31 is higher than the top end of the vertical section of the concave plate 3 is met, and if the top end of the vertical section of the concave plate 3 is higher than the top end of the vertical section of the L-shaped clamping plate 31, the top end of the vertical section of the L-shaped clamping plate 31 is required to be higher than the bottom of the material box 2 borne by the top plate 11 on the horizontal section belt body by a predetermined distance, and in this example, the top end of the vertical section of the L-shaped clamping plate 31 is higher than the top end of the vertical section of the concave plate 3 for the following description. Along the conveying direction, the lifting bar 41 is at least partially located in the region corresponding to the cartridge placement position and partially located in the region before reaching the cartridge placement position, so that the latter cartridge 2 can be fed to the cartridge placement position and the empty cartridge 2 which is already in the cartridge placement position and completes the lead frame discharge can be discharged.

The bottom of the top plate 11 is provided with a groove 12 penetrating along the length direction of the horizontal section belt body and used for being matched with the jacking strip 41 so as to be convenient for conveying of the adaptive annular conveying belt and form a certain guiding and limiting function.

When the feeding device is applied, the annular conveyor belt can control the conveying in a stepping mode, and the condition that when one feeding material box 2 reaches a material box placing position, the conveying is stopped, and after the lead frames in the material box 2 are all sent out, the next feeding material box is conveyed in a stepping mode is met. In this environment, the operator can take the cartridge 2 from the position where the cartridge was originally required to be placed, and release the operation to a larger operation space, that is, at two ends of the horizontal band, one end is used for assembling the cartridge 2 onto the top plate 11, and the other end is used for removing the empty cartridge 2 from the top plate 11. When the assembled material box 2 moves to the material box placing position along with the top plate 11 under the conveying of the annular conveying belt, when reaching a stepping position before the material box placing position, the telescopic rod 1 is lengthened through the lifting bar 41 to lift the material box 2 to a certain height, the material box 2 is lifted up by the height of the bottom end of the material box 2 slightly higher than the top end of the vertical section of the L-shaped clamping plate 31, then the jacking state is kept, the material box 2 which is currently jacked up is conveyed to a next stepping position through the matching of the top plate 11 and the lifting bar 41, namely, the material box placing position is in pause of conveying, then the lifting bar 41 is lowered, the material box 2 which is positioned at the material box placing position is lowered along with the lifting bar 41 and is received on the L-shaped clamping plate 31, after the material box 2 is unloaded, the material box 2 is jacked up again through the lifting bar 41, the annular conveying belt is conveyed again to a stepping position, the empty material box 2 moves downwards, and the gravity is contacted with the lifting bar 41, and the material box 2 is retracted from the lifting bar 1 and the telescopic rod 2 under the action of the top plate 11. The arrangement of the jacking strip 41 does not block and influence the normal conveying of the material box 2, the vertical air cylinders 4 are also arranged on two sides of the annular conveying belt, the length of the top plate 11 along the width direction of the annular conveying belt is larger than the width of the annular conveying belt and smaller than the length of the material box 2 in the direction, the material box 2 can be acted on by the jacking strip 41 and can be accepted by the L-shaped clamping plates 31 on the outer side, when the material box is placed, the material box can be fed in a descending mode after ascending, then the material is discharged along with conveying and descending after ascending, and the whole mechanism can normally operate.

In order to enable the cartridge 2 to keep better stability on the top plate 11, insertion holes can be formed in two sides of the top plate 11, and through holes corresponding to the insertion holes are formed in two walls of a groove at the bottom of the cartridge 2 and used for penetrating fixing pins. By inserting the fixing pins together during assembling the magazine 2, the stability during operation is improved, and subsequently, when the empty magazine 2 is fed, the magazine 2 is taken down again after the fixing pins are taken down.

The above description is only of the preferred embodiments of the present application and is not intended to limit the application, and it will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit and scope of the application.
