[0029] Reference Figures 2-6 The embodiment discloses a conveying chain based on end chain segment forward conveying, which comprises a first conveying chain 1 and a second conveying chain 2 arranged symmetrically, and a plurality of trays 3 for placing workpieces forward are arranged between the first conveying chain 1 and the second conveying chain 2. The first conveying chain 1 and the second conveying chain 2 are both provided with matched end chain segments 4 and end chain wheels 5. The two sides of one end of the tray 3 are respectively provided with protruding mounting shafts 6. One end of one of the mounting shafts 6 is mounted and connected with one side of the tray 3, and the other end of the mounting shaft 6 is mounted and connected with the chain of the corresponding first conveying chain 1. One end of the other mounting shaft 6 is mounted and connected with the other side of the tray 3, and the other end of the mounting shaft 6 is mounted and connected with the chain of the corresponding second conveying chain 2. Thus, after the mounting and connection of the tray 3, one end is mounted and connected, and the other end is equivalent to a free state. It should be noted that in the embodiment, the mounting and connection of the mounting shaft 6 and the chain can be that the mounting shaft 6 is inserted and connected in the center hole (not shown) of the roller 15 of the chain. Secondly, the mounting and connection of the mounting shaft 6 and the tray 3 and the roller 15 need to meet the condition that when the tray 3 runs to the end chain segment 4, the tray 3 still maintains the state of forward mounting and connection in the process of the chain running around the end chain wheel 5. Specifically, in the embodiment, the mounting and connection is realized by the following manner: the mounting shaft 6 and the center hole of the roller 15 are clearance-fitted, and the mounting shaft 6 can be mounted on the tray 3 by a fastener such as a screw or by welding.

[0030] Meanwhile, the end chain wheel 5 is also provided with a guide gear 7 and the two are drivingly connected through a transmission chain 8, so that the guide gear 7 can rotate together with the end chain wheel 5. Further, in the embodiment, the size and structure of the guide gear 7 are basically consistent with those of the end chain wheel 5, so that the guide gear 7 can run synchronously and at the same speed. It should be noted that the guide gear 7 can be arranged in front of or behind the end chain wheel 5 in the radial direction, and whether it is arranged in front of or behind can be set according to the position of the specific end chain segment 4 on the conveying chain and the conveying direction.

[0031] In the embodiment, the two sides of the other end of the tray 3 are respectively provided with the first guide wheels 9, that is, the two sides of the other end in the free state are respectively provided with the first guide wheels 9 which can be fitted into the tooth grooves 7-1 of the corresponding guide gears 7. Thus, when the tray 3 runs to the end section 4, the first guide wheels 9 gradually enter the corresponding tooth grooves 7-1 and run together with the guide gears 7, which is equivalent to providing support and driving for the other end of the tray 3 in the free state, so that the relative rotation between the tray 3 and the chain can exist to keep the tray 3 in the state of being positively connected when the tray 3 runs to the end section 4, so as to realize the positive placement of the workpiece 10 on the tray 3. Specifically, in the embodiment, when the tray 3 runs to the end section 4, the relative rotation between the mounting shaft 6 and the roller 15 occurs under the support and driving of the guide gears 7 on the first guide wheels 9, which is indirectly reflected in the state that the tray 3 still keeps the positive connection, while the chain runs around the end sprocket 5. At this time, the tray 3 which still keeps the positive connection can realize the positive placement of the workpiece 10 at the end section 4, and finally realize the positive conveying of the workpiece 10 at the end section 4.

[0032] Considering that it may be inconvenient to provide support for the first guide wheels 9 at the critical position in the conveying process of the end section 4, in the embodiment, the second guide wheels 11 are also symmetrically provided on the two sides of the other end of the tray 3. And in the state that the first guide wheels 9 are also symmetrically provided on the two sides of the other end of the tray 3, the second guide wheels 11 on the same side are located above the first guide wheels 9, so as not to hinder the support of the first guide wheels 9 in the tooth grooves 7-1 of the guide gears 7.

[0033] The first conveying chain 1 and the second conveying chain 2 both have horizontal sections 12, and the horizontal guide members 13 are arranged at the horizontal sections 12 to enable at least one of the first guide wheels 9 and the second guide wheels 11 to run thereon. Thus, the other end of the tray 3 in the free state in the conveying direction at the end section 4 and the horizontal section 12 can be supported, and at least one of the first guide wheels 9 and the second guide wheels 11 can be guided to run, so as to keep the positive connection of the tray 3.

[0034] Specifically, for the structure of the horizontal guide members 13, the following structure is mainly adopted in the embodiment. The horizontal guide members 13 include horizontal main guide members 13-1 and transition horizontal guide members 13-2, the horizontal main guide members 13-1 are for the first guide wheels 9 to run thereon, and the transition horizontal guide members 13-2 are for the second guide wheels 11 to run thereon.

[0035] Meanwhile, in order to keep the conveying chain running smoothly, in the embodiment, the mounting shaft 6 is also provided with a shaft guide wheel 14 which also runs along the horizontal main guide rail 13-1. Further, the chain roller 15 also runs along the horizontal main guide rail 13-1. It can be seen that the first guide wheel 9, the shaft guide wheel 14 and the roller 15 are supported and guided by the same horizontal main guide rail 13-1, which simplifies the overall design structure.

[0036] Further, the chain is also provided with a side roller 17, and the horizontal main guide rail 13-1 is also provided with a side guide plate 13-3, and the side roller 17 runs along the side guide plate 13-3.

[0037] In the embodiment, in order to further keep the first guide wheel 9 stable and smooth during the operation of the guide gear 7, the guide gear 7 is also provided with an arc-shaped guide rail 16 which is connected with the horizontal main guide rail 13-1 to support the first guide wheel 9 in the gear slot 7-1 to run along it.

[0038] In the embodiment, it is emphasized that the mounting shaft 6 is symmetrically located on both sides of one end of the tray 3, the first guide wheel 9 is symmetrically located on both sides of the other end of the tray 3, and the second guide wheel 11 is also symmetrically located on both sides of the other end of the tray 3, and the second guide wheel 11 on the same side is located above the first guide wheel 9. Wherein one end of the tray 3 and the other end of the tray 3 can be understood as one end or the other end in the conveying direction when the horizontal chain segment 12. In this way, the tray 3 can keep force balance when running at the end chain segment 4 or the horizontal chain segment 12, thereby providing protection for keeping the positive installation connection state.

[0039] It should be noted that in actual use, the conveying chain can be fitted to the rack of the equipment through the setting of the end chain wheel 5 and other components, and at the same time, each guide rail can also be fitted to the rack, thereby forming the required equipment structure.

[0040] Secondly, the specific structure of the tray 3 is not particularly limited in the embodiment, and the positive placement of the workpiece 10 can be met. Of course, in other embodiments, some positioning structures can be provided to position the workpiece 10, or some tooling structures can be designed to clamp the workpiece 10, which is within the protection scope of the present application.

[0041] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not limiting, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims, which are all within the protection scope of the present application.
