For ease of illustration, only the content related to the embodiments of the present application is shown.

[0055] Please refer to Figures 1 to 3 The embodiments of the present application provide a tray changing device 100, which comprises a first conveying mechanism 110 and a second conveying mechanism 120. The first conveying mechanism 110 and the second conveying mechanism 120 are arranged along a first direction F1, and the second conveying mechanism 120 is arranged downstream of the first conveying mechanism 110 along the first direction F1.

[0056] The first conveying mechanism 110 is a mechanism for separating a material W and an initial tray T0, and conveying the material W along the first direction F1. The material W can be a plate. Specifically, the first conveying mechanism 110 comprises a plurality of first conveying units 111 arranged at intervals. The plurality of first conveying units 111 define a first accommodation space Q1 for accommodating the initial tray T0 therebetween. For example, Figure 4 For example, Figure 4 Fig. 4 shows a structural schematic view of the first conveying unit 111 in a state of use, illustrating a case where the initial tray T0 is accommodated in the first accommodation space Q1. For ease of illustration, only the content related to the embodiments of the present application is shown.Figure 3 and Figure 4 The plurality of first conveying units 111 are used to jointly carry the material W arranged on the initial tray T0 and convey the material W along the first direction F1. That is, the plurality of first conveying units 111 are independent of each other, and the spacing between each first conveying unit 111 constitutes the first accommodation space Q1. The plurality of first conveying units 111 can be synchronously driven by the same driving member or synchronously driven by a plurality of driving members one by one, which is not specifically limited here. The driving member can be drivingly connected to the corresponding first conveying unit 111 by means of relevant transmission components, which are not specifically limited here. For example, the relevant transmission components can be a gear set and a shaft assembly, etc. For another example, the relevant transmission components can be belt transmission related components, etc. The relevant transmission components can be set according to specific use requirements, which are not specifically limited here.

[0057] The first conveying unit 111 is a unit with conveying function. Specifically, the first conveying unit 111 can include at least one first conveying roller 111a, and the extension direction of the rotation axis of the first conveying roller 111a is perpendicular to the first direction F1. In this way, when the first conveying roller 111a is driven to rotate by the relevant driving member, the material W placed on the first conveying roller 111a can move along the first direction F1 under the action of the rotation of the first conveying roller 111a, thereby realizing the movement of the material W along the first direction F1. For example, the first conveying unit 111 includes two first conveying rollers 111a. Of course, the number of first conveying rollers 111a provided in each first conveying unit 111 can be the same or different, which is not specifically limited here. Figure 3

[0058] When the tray fork places the initial tray T0 arranged with the material W on the first conveying mechanism 110, the initial tray T0 can fall under the action of gravity and be accommodated in the first accommodation space Q1, and the material W is carried on the first conveying unit 111. In this way, by providing the first conveying mechanism 110, the separation of the material W and the initial tray T0 can be realized, and the de-tray operation is completed.

[0059] With reference to Figure 5 , Figure 5 The second conveying mechanism 120 is a mechanism for receiving the material W conveyed by the first conveying mechanism 110 along the first direction F1 and arranging the material W on the target tray T1, Figure 5 ​The second conveying mechanism 120 is provided with the target tray T1. Specifically, the second conveying mechanism 120 comprises a plurality of second conveying units 121 arranged at intervals, and a second accommodating space Q2 is defined between the plurality of second conveying units 121 for accommodating the target tray T1. The second conveying units 121 are used to convey the material W along the first direction F1 and move up and down along the second direction F2 to carry the material W conveyed by the first conveying mechanism 110 and move the material W to the target tray T1. The first direction F1 and the second direction F2 are perpendicular to each other. In the embodiment, the second direction F2 is a vertical direction, and the first direction F1 is a horizontal direction. The plurality of second conveying units 121 are independent of each other, and the intervals between the second conveying units 121 constitute the second accommodating space Q2. The plurality of second conveying units 121 can be synchronously driven by the same driving member or synchronously driven by a plurality of driving members one by one, which is not limited here. The driving member can be drivingly connected to the corresponding second conveying unit 121 by means of related transmission components, which are not limited here. The related transmission components can be understood with reference to the foregoing embodiments of the related transmission components, which are not repeated here. It can be understood that the components for driving the second conveying units 121 to convey the material W along the first direction F1 and the components for driving the second conveying units 121 to move up and down along the second direction F2 are different driving components.

[0060] The second conveying unit 121 is a unit with conveying function. Specifically, the second conveying unit 121 can comprise at least one second conveying roller 121a, and the extending direction of the rotation axis of the second conveying roller 121a is perpendicular to the first direction F1. In this way, when the second conveying roller 121a is driven to rotate by the related driving member, the material W carried on the second conveying roller 121a can move along the first direction F1 under the action of the rotation of the second conveying roller 121a, thereby realizing the movement of the material W along the first direction F1. Figure 3 For example, it is shown that the second conveying unit 121 comprises a plurality of second conveying rollers 121a. Of course, the number of second conveying rollers 121a provided in each second conveying unit 121 can be the same or different, which is not limited here.

[0061] For example, the components for driving the second conveying units 121 to convey the material W along the first direction F1 can be a driving motor (not shown in the figure) and a belt transmission assembly (not shown in the figure), and the second conveying roller 121a can be driven to rotate by the driving motor and the belt transmission assembly. The components for driving the second conveying units 121 to move up and down along the second direction F2 can be a lifting unit I, which can be a hydraulic lifting mechanism, a pneumatic lifting mechanism, an electric lifting mechanism, or a scissor-type lifting mechanism, which is not limited here.

[0062] During the lifting and lowering movement of the second conveying unit 121 along the second direction F2, the second conveying unit 121 can be extended or retracted relative to the target tray T1. Specifically, when the second conveying unit 121 is extended relative to the target tray T1, the carrying surface of the second conveying unit 121 is located above the carrying surface of the target tray T1, at this time, the second conveying unit 121 can receive the material W conveyed by the first conveying mechanism 110 along the first direction F1. Subsequently, when the second conveying unit 121 is retracted relative to the target tray T1, the carrying surface of the second conveying unit 121 is located below the carrying surface of the target tray T1, at this time, the material W carried by the second conveying unit 121 is carried by the target tray T1. That is, with the lifting and lowering movement of the second conveying unit 121 along the second direction F2, the tray adding operation of the material W can be realized.

[0063] Therefore, by configuring the first conveying mechanism 110 to include a plurality of first conveying units 111 arranged at intervals, when the initial tray T0 carrying the material W is placed on the first conveying mechanism 110, the initial tray T0 falls into the first accommodation space Q1 defined between the first conveying units 111 under the action of gravity, and the material W is carried on the first conveying units 111, thereby realizing the separation of the material W from the initial tray T0. By configuring the second conveying mechanism 120 to include a plurality of second conveying units 121 arranged at intervals, when the target tray T1 is placed on the second conveying mechanism 120, the target tray T1 can fall into the second accommodation space Q2 defined between the second conveying units 121 under the action of gravity. Since the second conveying unit 121 is configured to be capable of conveying the material W along the first direction F1 and lifting and lowering movement along the second direction F2, the second conveying unit 121 can receive the material W conveyed by the first conveying mechanism 110 at a position extended from the target tray T1, adjust the position of the material W relative to the target tray T1 along the first direction F1, and then lower along the second direction F2, so that the material W is carried by the target tray T1, thereby completing the tray adding operation of the material W. Therefore, by using the tray changing device 100 provided in the embodiments of the present application, the tray removing operation and the tray adding operation of the material W can be realized, thereby realizing the automatic tray changing operation, and improving the operation efficiency of the tray changing.

[0065] In some embodiments, please continue to refer to Figure 1 , and refer to Figure 6 and Figure 7The first conveying mechanism 110 further comprises a first transfer unit 112. The first transfer unit 112 is configured to transfer the first conveying units 111 along a third direction F3. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. In some embodiments, the first direction F1 and the third direction F3 are horizontal directions, and the second direction F2 is a vertical direction.

[0066] The first transfer unit 112 is configured to carry and move the first conveying units 111, and is capable of transferring the first conveying units 111 to different positions. Specifically, the first transfer unit 112 is configured to carry the first conveying units 111 along the third direction F3. Figure 6 and Figure 7 For example, the first transfer unit 112 can comprise a first driving member 112a, a first transmission assembly 112b, a first mounting member 112c and a first guide rail 112d. The first driving member 112a is connected to an input end of the first transmission assembly 112b. An output end of the first transmission assembly 112b is connected to the first mounting member 112c. The first mounting member 112c is configured to mount all the first conveying units 111. The first mounting assembly is slidably connected to the first guide rail 112d along the third direction F3 via a sliding block (not shown in the figure). The first transmission assembly 112b can comprise a gear (not shown in the figure) and a rack (not shown in the figure) connected in mesh. The first driving member 112a can be a motor. The first driving member 112a is connected to the gear, and the rack is connected to the first mounting member 112c. Further, the tray changing device 100 can further comprise a first frame G1. The first transfer unit 112 is arranged on the first frame G1.

[0067] In this way, the first transfer unit 112 can be configured to move the first conveying units 111 along the third direction F3, so as to adjust the position of the material W carried by the first conveying units 111 along the third direction F3. This is conducive to conveying the material W to the second conveying mechanism 120 according to the size and state of the material W.

[0068] In some embodiments, please continue to refer to Figure 1 , Figure 2 and Figure 6 The tray changing device 100 further comprises an adjusting mechanism 130. The adjusting mechanism 130 is arranged on one side of the first conveying mechanism 110 along the third direction F3. The adjusting mechanism 130 is configured to cooperate with the first transfer unit 112 to adjust the pose of the material W carried by the first conveying units 111.

[0069] The adjusting mechanism 130 is a mechanism that can be used to adjust the pose of the material W. Since the first conveying unit 111 can move along the third direction F3 under the driving of the first transfer unit 112, that is, the adjusting mechanism 130 is located on the moving path of the first conveying unit 111 moving along the third direction F3, so that the material W carried by the first conveying unit 111 can be matched with the adjusting mechanism 130 during the movement of the first conveying unit 111 along the third direction F3, so that the adjusting mechanism 130 can be used to adjust the pose of the material W. In this way, it is further beneficial to convey the material W to the second conveying mechanism 120 according to the size and state of different materials W.

[0070] In some embodiments, please continue to refer to Figure 1 、 Figure 2 and Figure 6 , the adjusting mechanism 130 includes a plurality of adjusting rollers 131 arranged along the first direction F1, and the extending directions of the rotation axes of the adjusting rollers 131 are parallel to each other along the second direction F2; the plurality of adjusting rollers 131 are used to abut against the material W supported by the first conveying unit 111 along the third direction F3 to adjust the pose of the material W.

[0071] In this way, since the adjusting rollers 131 are rotatably arranged, after the material W abuts against the adjusting rollers 131 and the pose is adjusted, the first conveying unit 111 can be directly used to convey the material W along the first direction F1, at this time, the adjusting rollers 131 are rotated under the action of the material W, thereby facilitating the conveying of the material W.

[0072] In some embodiments, please continue to refer to Figure 1 、 Figure 2 and Figure 6 , the changing device 100 further includes a first detection member J1 arranged on the adjusting mechanism 130, and the first detection member J1 is used to detect whether the pose of the material W is in a target pose.

[0073] Specifically, the first detection member J1 can be arranged in a plurality along the first direction F1. Further, the first detection member J1 can determine whether the pose of the material W is in the target pose by detecting whether the material W is in place. It can be understood that when the material W abuts against the adjusting rollers 131, the detection member detects that the material W is in place, that is, it can be determined that the pose of the material W is in the target pose. Exemplarily, the first detection member J1 can be a photoelectric sensor or an infrared sensor, etc. without specific limitation here. In the case that the first detection member J1 detects that the pose of the material W is in the target pose, the first transfer unit 112 stops transferring the first conveying unit 111 to move along the third direction F3.

[0074] Therefore, by arranging the first detection member J1, not only the transfer distance of the first transfer unit 112 can be controlled, but also the pose of the material W can be adjusted, so as to adjust the pose of the material W to the target pose.

[0075] Of course, in other embodiments, the material W can also be abutted against the adjusting roller 131 by pre-setting the transfer distance of the first transfer unit 112. The pre-set transfer distance can be determined according to different materials W, which is not limited here.

[0076] In some embodiments, please continue to refer to Figure 4 and Figure 7 The first conveying mechanism 110 further comprises a limiting member 113. The limiting member 113 is arranged in the first accommodating space Q1, and the limiting member 113 is configured to limit the initial tray T0.

[0077] Specifically, the limiting member 113 defines a limiting passage p. In combination with reference to Figure 4 When the tray fork places the initial tray T0 carrying the material W on the first conveying unit 111, the initial tray T0 falls into the first accommodating space Q1 under the action of gravity, and the material W is carried on the first conveying unit 111. The protruding part of the bottom of the initial tray T0 is limited by the limiting member 113 through the limiting passage p, so that the initial tray T0 is limited in the first accommodating space Q1. Further, the cross-sectional area of the limiting passage p of the initial tray T0 along the second direction F2 first decreases and then remains unchanged, which is beneficial to the protruding part of the bottom of the initial tray T0 to enter the limiting passage p.

[0078] Therefore, by arranging the limiting member 113, not only the initial tray T0 accommodated in the first accommodating space Q1 can be limited, but also the tray fork can place the initial tray T0 between the first conveying units 111.

[0079] Figure 8 The structure schematic diagram of the cooperation of the target tray T1, the first positioning member D1 and the second positioning member D2 in some embodiments of the present application is shown; for the convenience of description, only the contents related to the embodiments of the present application are shown.

[0080] In some embodiments, please continue to refer to Figure 5 and Figure 8 The tray changing device 100 further comprises a first positioning member D1 arranged on one side of the target tray T1 along the first direction F1, and the first positioning member D1 is located on the movement path of the material W moving along the first direction F1; and / or, the tray changing device 100 further comprises a second positioning member D2 arranged on one side of the target tray T1 along the third direction F3, and the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0081] With the first positioning member D1 disposed on the target tray T1 on the side close to the first conveying mechanism 110 along the first direction F1 as an example, after the second conveying unit 121 receives the material W conveyed by the first conveying unit 111, the second conveying unit 121 descends along the second direction F2. Subsequently, the second conveying unit 121 can move along the first direction F1 away from the first conveying unit 111 by a certain distance, so that the material W can abut against the first positioning member D1. Then, the second conveying unit 121 continues to descend along the second direction F2, and the material W is completely carried on the target tray T1, completing the tray adding operation. The case where the first positioning member D1 is disposed on the side away from the first conveying mechanism 110 along the first direction F1 of the target tray T1 can be understood with reference to the case where the first positioning member D1 is disposed on the side close to the first conveying mechanism 110 along the first direction F1 of the target tray T1, which will not be repeated here. It should be noted that the distance of the second conveying unit 121 descending along the second direction F2 can be adjusted according to actual use, which will not be specifically limited here.

[0082] In this way, by arranging the first positioning member D1, the material W can be placed on the corresponding target tray T1 with the same reference, thereby facilitating the turnover of the target tray T1 carrying the material W. By arranging the second positioning member D2, the material W is further positioned, so that the material W can have substantially the same reference with respect to the corresponding target tray T1.

[0083] In some embodiments, please continue to refer to Figure 1 , Figure 2 and Figure 5 , the second conveying mechanism 120 further comprises a second transfer unit 122. All the second conveying units 121 are arranged on the second transfer unit 122, and the second transfer unit 122 is used to transfer the second conveying units 121 along the first direction F1.

[0084] The second transfer unit 122 is a unit for carrying and moving the second conveying units 121, and can transfer the second conveying units 121 to different positions. The second transfer unit 122 can be understood with reference to the first transfer unit 112, and the structures of the two can be the same or different. Specifically, with Figure 1 , Figure 2 and Figure 5 as examples, the second transfer unit 122 can comprise a second guide rail 122a, and all the second conveying units 121 are arranged on the aforementioned lifting unit I, the lifting unit I is arranged on the second frame body G2, and the bottom of the second frame body G2 can be provided with a guide wheel E which can move along the second guide rail 122a along the first direction F1. The related driving components can be connected to the second frame body G2 to drive the second frame body G2 to move along the first direction F1. In this way, the second transfer unit 122 can transfer the second conveying units 121 along the first direction F1.

[0085] Thus, by arranging the second transfer unit 122, the continuous operation of the material W turnover can be facilitated.

[0088] In some embodiments, please continue to refer to Figure 1 , Figure 2 and Figure 5 , the tray changing device 100 further comprises a third detection member J3 arranged on the transfer path of the second transfer unit 122, and the third detection member J3 is used to detect the profile of the target tray T1 and the material W carried on the target tray T1, so as to determine whether the target tray T1 is suitable for the material W. For example, the third detection member J3 can be a vision sensor.

[0089] Thus, by arranging the third detection member J3, the tray changing process of the material W can be more reliable.

[0090] In some embodiments, the tray changing device 100 further comprises a buffer member (not shown in the figure) arranged on the transfer path of the second transfer unit 122. The buffer member is a component used to reduce impact force and absorb energy.

[0091] Thus, by arranging the buffer member, the second transfer unit 122 can be protected, the vibration can be reduced, and the stability of the transfer of the second transfer unit 122 can be improved, so as to protect the material W.

[0092] In some embodiments, please continue to refer to Figure 1 and Figure 2 , the tray changing device 100 further comprises a fourth detection member J4, and the fourth detection member J4 is used to detect whether the target tray T1 exists on the second conveying mechanism 120. For example, the fourth detection member J4 can be a photoelectric sensor, an ultrasonic sensor, etc., which is not limited here.

[0093] Thus, by arranging the fourth detection member J4, the target tray T1 can be supplemented when there is no target tray T1 placed on the second conveying mechanism 120, so as to realize the continuous operation of the material W tray changing, and further improve the work efficiency. Thus, by arranging the fourth detection member J4, the target tray T1 can be supplemented when there is no target tray T1 placed on the second conveying mechanism 120, so as to realize the continuous operation of the material W tray changing, and further improve the work efficiency.

[0094] In some embodiments, please continue to refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , all the first conveying units 111 are arranged in multiple rows along the first direction F1 and in multiple columns along the third direction F3; the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other; and / or, all the second conveying units 121 are arranged in multiple rows along the first direction F1 and in multiple columns along the third direction F3; the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0095] In this way, all the first conveying units 111 are arranged in an array, which not only can improve the carrying capacity and carrying stability of the first conveying mechanism 110, but also is conducive to forming the first accommodating space Q1 accommodating the initial tray T0. All the second conveying units 121 are arranged in an array, which not only can improve the carrying capacity and carrying stability of the second conveying mechanism 120, but also is conducive to forming the second accommodating space Q2 accommodating the target tray T1.

[0096] In some embodiments, please continue to refer to Figure 1 and Figure 2 , the tray changing device 100 further comprises a controller 140, the controller 140 is electrically connected with the first conveying mechanism 110 and the second conveying mechanism 120, and the controller 140 is used for controlling the action of the first conveying mechanism 110 and the action of the second conveying mechanism 120. Further, the controller 140 is also electrically connected with the first detection member J1, the second detection member J2, the third detection member J3 and the fourth detection member J4 respectively. The controller 140 is also used for controlling the conveying action of the corresponding conveying unit and the transfer action of the corresponding transfer unit according to the detection signals of the above detection members.

[0097] In this way, by setting the controller 140, the automatic and continuous operation of the tray changing device 100 is facilitated, so as to further improve the work efficiency.

[0098] To sum up, in the tray changing device 100 provided by the embodiments of the present application, through the cooperation between the first conveying mechanism 110, the second conveying mechanism 120, the adjusting mechanism 130 and the detection members, different kinds and sizes of initial trays T0 can be compatible, different materials W can be automatically changed to target trays T1 with the same standard, and the materials W after changing trays are all on the same reference. Therefore, not only the work efficiency can be improved, but also the turnover of the materials W after changing trays is facilitated. For example, when the materials W are stored by the vertical storage mode, through the use of the tray changing device 100, the materials W can be more safely and stably turned over, so that the materials W are put into the warehouse with a unified reference, thereby facilitating the subsequent operation on the materials W. The subsequent operation on the materials W can be feeding, cutting and the like, which are not specifically limited herein.
