[0040] Example:

[0041] See also Figures 1 to 7The material transfer device in the preferred embodiment of the utility model includes a first material conveying mechanism arranged along a first direction and a second material conveying mechanism arranged along a second direction, and the first material conveying mechanism is at least partially connected to the second material conveying mechanism; the first material conveying mechanism includes a material conveying platform 2 arranged along the first direction, and a storage rack 3 mounted on the material conveying platform 2, the storage rack 3 is provided with a receiving mechanism that can move along one direction of the horizontal plane, and a storage tray 6 is placed on the receiving mechanism, and the projection of the storage tray 6 along the third direction falls on the material conveying platform 2.

[0042] Specifically, the present application realizes the transfer of materials between different workstations on the platform through a first material transfer mechanism and a second material transfer mechanism; and, by setting up a material storage rack 3 on the material transfer table 2 and utilizing the movement of a receiving mechanism to realize the loading or lowering of the material storage tray 6, the components in the material storage tray 6 can be transferred to different workstations through the material transfer table 2, so as to realize the automated assembly of the optical fiber connector.

[0043] Specifically, as a preferred embodiment of the present invention, the first direction in the present application is one of the directions on the horizontal plane, the second direction is a direction in the horizontal plane perpendicular to the first direction, and the third direction is a vertical direction. Optionally, when the present application does not need to consider the layout space of the material transfer device, the first direction and the second direction can also be in the same direction.

[0044] Preferably, the present application further comprises a processing table 1, and the first material transmission mechanism and the second material transmission mechanism are both arranged on the processing table 1. In addition, other device components such as fiber insertion, spring insertion, and rubber plug insertion can also be arranged on the processing table 1, and the first material transmission mechanism, the second material transmission mechanism, and other components are arranged in coordination to realize the automatic assembly of the optical fiber connector.

[0045] Further, as a preferred embodiment of the utility model, the storage rack 3 in the present application includes a plurality of support rods extending along the third direction, the plurality of support rods are arranged on both sides of the transmission direction of the material transmission platform 2, and the plurality of support rods enclose a storage tray 6. Correspondingly, a swing assembly 4 is extended from each support rod toward the material transmission platform 2, the swing assembly 4 and the storage tray 6 at least partially overlap along the third direction, and the swing assembly 4 is rotatably connected to the support rod through a rotating shaft 5. Specifically, the storage tray 6 in the present application is a square disc-shaped structure, and the plurality of support rods are arranged at the four corners of the storage tray 6. Then, by arranging the swing assembly 4 on the support rod, each swing assembly 4 extends below the storage tray 6. When the swing assembly 4 swings around the rotating shaft 5, the corresponding position of the swing assembly 4 in the horizontal direction will also change, so as to achieve the misalignment of the swing assembly 4 and the storage tray 6 in the third direction, and complete the fixed-point lowering of the storage tray 6. It is worth noting that when the present application realizes the support of the storage tray 6 through multiple swing components 4, each swing component 4 is located at the same horizontal height to achieve support for each corner of the storage tray 6.

[0046] Further, as a preferred embodiment of the utility model, the material storage rack 3 in the present application is provided with a step surface 15, the rotating shaft 5 is slightly higher than the step surface 15 along the third direction, and the swing assembly 4 is connected to the step surface 15. By controlling the rotating shaft and the rotating direction of the swing assembly 4, it is realized that the swing assembly 4 can only rotate in one direction. When a plurality of material storage trays 6 are supported on the swing assembly 4, the swing assembly 4 is restricted by the step surface 15 and cannot rotate downward along the third direction, thereby realizing stable storage of the material storage trays 6.

[0047] Optionally, a connecting rod may be provided between the multiple support rods of the present application, and then a swing assembly 4 is provided on the connecting rod, so as to complete the support of each side of the storage tray 6 through the swing assembly 4.

[0048] Further, as a preferred embodiment of the utility model, the material storage rack 3 of the present application is provided with an auxiliary material receiving plate 14, which is arranged below the swing assembly 4 along the third direction, and the auxiliary material receiving plate 14 can reciprocate along the third direction. Specifically, when the auxiliary material receiving plate 14 moves upward along the third direction, the auxiliary material receiving plate 14 abuts against the lower surface of the swing assembly 4, the swing assembly 4 rotates upward around the rotation axis 5, and the swing assembly 4 and the material storage plate 6 are misaligned in the third direction; when the auxiliary material receiving plate 14 moves downward along the third direction, the swing assembly 4 rotates downward around the rotation axis 5, and the projections of the swing assembly 4 and the material storage plate 6 in the third direction gradually overlap.

[0049] Furthermore, as a preferred embodiment of the utility model, the auxiliary material receiving tray 14 of the present application is provided with a protrusion 16, and the side of the protrusion 16 away from the swing component 4 is a vertical plane, which is perpendicular to the auxiliary material receiving tray 14, and the vertical planes of multiple protrusions 16 away from the swing component 4 are adapted to the outer contour of the storage tray 6 to form a accommodating space for the storage tray 6. When the storage tray 6 falls on the auxiliary material receiving tray 14, the auxiliary material receiving tray 14 can realize the positioning of the storage tray 6 to ensure the stability of the storage tray 6 moving along the third direction.

[0050] Furthermore, as a preferred embodiment of the utility model, the protrusion 16 of the present application is an inclined surface facing the swing component 4, and the inclined surface matches the swing component 4. When the auxiliary material receiving plate 14 moves upward along the third direction until it abuts against the swing component 4, the inclined surface is connected to the swing component 4, and the swing component 4 rotates upward around the rotation axis 5; when the auxiliary material receiving plate 14 moves downward along the third direction, the swing component 4 is connected to the inclined surface, and the swing component 4 rotates downward around the rotation axis 5. The matching of the swing component 4 and the inclined surface ensures the rotation stability of the swing component 4.

[0051] Optionally, the driving mechanism for controlling the auxiliary material receiving tray 14 to move along the third direction may be a servo motor or a servo cylinder, and the driving mechanism may be controlled by a PLC to achieve automatic delivery of the material storage tray 6 .

[0052] Further, as an optional embodiment of the present invention, a translation assembly is provided on the multiple support rods in the present application, and the translation assembly can move in the horizontal direction to move toward or away from the storage tray 6. When the translation assembly moves toward the storage tray 6, the translation assembly falls below the storage tray 6 to achieve the acceptance of the storage tray 6; when the translation assembly moves away from the storage tray 6, there is an empty space below the storage tray 6, and the storage tray 6 can fall on the material transfer platform 2. Correspondingly, the present application can also simultaneously set a swing assembly 4 and a translation assembly to jointly achieve the acceptance and lowering of the storage tray 6. Specifically, the receiving mechanism in the present application can be a swing assembly 4 and / or a translation assembly.

[0053] Further preferably, the present application also has placement notches 7 on both sides of the lower side of the material storage tray 6 facing the swing assembly 4, and the swing assembly 4 partially extends into the placement notches 7. Here, the swing assembly 4 partially extends into the placement notches 7, which means that the swing assembly 4 can fall on the placement notches 7 along the third direction to receive the material storage tray 6. The setting of the placement notches 7 can appropriately reduce the height difference between the material storage tray 6 and the material transfer platform 2 to ensure that the material storage tray 6 falls stably on the material transfer platform 2.

[0054] Further preferably, there are multiple storage racks 3 in the present application, and the multiple storage racks 3 are arranged in sequence along the first direction, and each storage rack 3 is provided with a receiving mechanism and a storage tray 6. In the assembly process of the optical fiber connector, multiple components such as springs, rubber plugs and ferrules are involved, and the shapes and sizes of the components are different, and it is impossible to use a single storage tray 6 to place all the components. The present application corresponds to setting up multiple storage racks 3, and different components are stably placed through different storage trays 6, so as to facilitate the stable placement of components in subsequent processes.

[0055] Further preferably, there are multiple storage trays 6 in the present application, and the multiple storage trays 6 are stacked in sequence along the first direction. In order to solve the problem of adding parts to the storage tray 6, the present application corresponds to vertically stacking multiple storage trays 6 to achieve a continuous supply of parts. At the same time, the placement gaps 7 on both sides of the storage tray 6 reserve swing time for the swing assembly 4. When the current storage tray 6 falls, the swing assembly 4 swings back and falls on the placement gap 7, so that the next storage tray 6 can be stably received.

[0056] Further, as a preferred embodiment of the present utility model, the second material transfer mechanism in the present application includes a sliding assembly arranged along the second direction, and a clamping assembly that can be extended and retracted along the third direction is slidably provided on the sliding assembly, and the projection of the clamping assembly along the third direction falls on the material transfer platform 2. Specifically, the second material transfer mechanism in the present application is erected above the material transfer platform 2 through a frame structure, and the clamping assembly clamps the parts in the storage tray 6 through vertical movement, and the sliding assembly correspondingly drives the clamping assembly to move along the second direction to transport the parts from the station of the first material transfer mechanism to other processing stations.

[0057] Furthermore, the material transfer platform 2 in the present application includes a transfer tray 13 arranged at intervals along the first direction, and the notches on the transfer tray 13 are adapted to the outer contour of the storage tray 6. When the storage tray 6 falls on the transfer tray 13, the transfer tray 13 can just fix the storage tray 6 to achieve stable transfer of the storage tray 6. Preferably, the transfer tray 13 is vertically arranged below the auxiliary material receiving tray 14.

[0058] Furthermore, if Figure 4As shown, the material storage tray 6 in the present application is provided with a plurality of material placement slots 12, and each material placement slot 12 is composed of two cross-arranged strip openings, and the clamping end of the clamping assembly can at least partially extend into one of the strip openings. Since the sizes of components such as springs, rubber plugs, and core inserts are relatively small, conventional placement tables will cause the components to shake, and the clamping assembly cannot accurately clamp the components, which can easily cause damage to the components. Conventional groove structures can fix components, but will cause problems in accessing components. The present application corresponds to setting the material placement slots 12 as cross-arranged strip openings, wherein one strip opening is used to place the above-mentioned springs, rubber plugs or core inserts, and the other strip opening is used for the clamping assembly to extend into, so as to achieve stable clamping of the springs, rubber plugs or core inserts.

[0059] Furthermore, as an optional embodiment of the utility model, a plurality of core insertion placement slots are provided on the storage tray 6 in the present application, and the depth of the core insertion placement slots is not greater than the thickness of the core insertion, so that the core insertion can be partially extended from the core insertion slots to facilitate the removal and placement of the core insertion.

[0060] Furthermore, the sliding assembly in the present application includes a first sliding rail 8 and a second sliding rail 9 arranged side by side along a first direction, and a first clamping mechanism 10 and a second clamping mechanism 11 are respectively provided on the first sliding rail 8 and the second sliding rail 9. Since the present application involves the use of a variety of parts, it is necessary to transport springs, rubber plugs or inserts to different stations for processing. Therefore, the present application sets the first sliding rail 8 and the second sliding rail 9 accordingly, and uses the first clamping mechanism 10 and the second clamping mechanism 11 to respectively take different parts and transport them to different processing stations. Optionally, the present application can also continue to set a third sliding rail and a third clamping assembly side by side with the first sliding rail 8 according to demand, and the number of sliding rails and clamping mechanisms can be adjusted according to the number of parts.

[0061] Further preferably, the clamping gap of the clamping end of the first clamping mechanism 10 is different from the clamping gap of the clamping end of the second clamping mechanism 11. Specifically, since the spring, rubber plug or plug in this application has different structural sizes and shapes, it is necessary to select clamps of adapted shapes to complete the clamping process of different components.

[0062] Alternatively, if Figure 6 As shown, when the first clamping mechanism 10 in the present application clamps the spring, the end of the clamping jaw needs to form an inwardly recessed arc-shaped notch to adapt to the outer contour of the spring, so as to achieve stable clamping of the spring without damaging the spring.

[0063] Alternatively, if Figure 7 As shown, when the second clamping mechanism 11 in the present application is used to clamp the ferrule, the second clamping mechanism 11 is a suction nozzle structure, which realizes the suction of the ferrule through negative pressure adsorption.

[0064] Preferably, the material transfer platform 2, the first sliding rail 8 and the second sliding rail 9 in the present application are correspondingly provided with driving structures, such as a driving motor or a driving cylinder, etc., to respectively realize the transmission of the material transfer platform 2 and the movement of the first clamping mechanism 10 and the second clamping mechanism 11 in the second direction.

[0065] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
