Description

Technical Field

[0001] The present application relates to the technical field of material transportation, and in particular to a material transport vehicle and an operating device. Background Art

[0002] When the material is produced, the material is transferred from the material transport vehicle to the rack for production operation, and then transferred to the material transport vehicle after the production operation. As the material transport vehicle moves, the material can be transferred to different areas of the rack. The materials before the production operation and the materials after the production operation need to be stacked separately on the material transport vehicle. In the related art, the materials before and after the operation are placed side by side on the material transport vehicle, and the material transport vehicle occupies a large area, which is not conducive to large-scale material production operations. Utility Model Content

[0003] In view of this, the present application provides a material transport vehicle and an operating device, which are helpful in reducing the occupied area of ​​the material transport vehicle.

[0004] One embodiment of the present application provides a material transport vehicle for transporting materials. The material transport vehicle includes a base, a first loading platform, a bracket and a second loading platform. The first loading platform is configured to carry materials along a first direction. The first loading platform is arranged on the base. The bracket is arranged on the base. The bracket is configured to be able to slide in the forward and reverse directions relative to the first loading platform along a second direction. The second direction is perpendicular to the first direction. The second loading platform is configured to carry materials along the first direction. The second loading platform is arranged on the bracket and is spaced apart from the first loading platform along the first direction. The second loading platform is configured to be able to move to a first position and a second position. When the second loading platform moves to the first position, at least part of the projection of the second loading platform overlaps with the first loading platform in the opposite direction of the first direction. When the second loading platform moves to the second position, the area of ​​the projection of the second loading platform overlapping with the first loading platform in the opposite direction of the first direction is reduced compared to when it is in the first position.

[0005] In the above embodiment, the first loading platform and the second loading platform carry materials respectively and stack them to form different material piles, so that the material transport vehicle can simultaneously transport materials before and after production operations. The distribution directions of the first loading platform and the second loading platform are parallel to the direction in which the materials are stacked on the two. When the second loading platform is in the first position, the area where it is located at least partially overlaps with the area where the first loading platform is located in the direction perpendicular to the direction of carrying the materials. Then, the positions of the materials in different material piles can at least partially overlap in the direction perpendicular to the stacking, so that the area occupied by the materials on the material transport vehicle is reduced, which is conducive to reducing the area occupied by the material transport vehicle, so as to expand the scale of material production operations. When the second loading platform is in the second position, the part of the area where it is located in the direction perpendicular to the direction of carrying the materials is reduced, so that the second loading platform is staggered with the first loading platform in the direction perpendicular to the material stacking, so as to facilitate stacking the materials on the first loading platform or taking the materials out of the first loading platform. By setting up the bracket, the second loading platform can be placed in the first position so that the second loading platform and the first loading platform at least partially overlap in a direction perpendicular to the first direction, and the second loading platform can be moved to the second position to facilitate the loading and unloading of materials on the first loading platform, thereby improving the efficiency of the material transport vehicle in transferring materials while reducing the occupied area of ​​the material transport vehicle, thereby facilitating the expansion of the scale of material production operations.

[0006] In some embodiments of the present application, the projection of the first loading platform in the reverse direction along the first direction is located within the range of the base. When the second loading platform moves to the first position, the projection of the second loading platform in the reverse direction along the first direction is located within the range of the base. When the second loading platform moves to the second position, the projection of the second loading platform in the reverse direction along the first direction is at least partially located outside the range of the base.

[0007] In the above embodiment, when the second loading platform moves to the first position, the first loading platform and the second loading platform are both within the range of the base in a direction perpendicular to the first direction, so as to plan the storage position and moving path of the material transport vehicle according to the size of the occupied area of ​​the base. When the second loading platform moves to the second position, it can be moved out of the range of the base in a direction perpendicular to the first direction so as to be staggered with the first loading platform in a direction perpendicular to the first direction, so as to take and place materials on the first loading platform, thereby reducing the occupied area of ​​the base and further reducing the occupied area of ​​the material transport vehicle.

[0008] In some embodiments of the present application, the bracket includes a first connecting portion, a second connecting portion and a third connecting portion. The first connecting portion is slidably connected to the base. The second connecting portion is connected to the second loading platform. Along the second direction, the extension length of the first connecting portion is greater than the extension length of the second connecting portion. The third connecting portion is connected to the first connecting portion and the second connecting portion.

[0009] In the above embodiment, the third connection part connects the first connection part and the second connection part, so that the second loading platform can be arranged on the base. In the second direction, the first connection part is longer than the second connection part, which can reduce the space occupied by the second connection part while maintaining the second loading platform and the second connection part, so as to facilitate the taking and placing of materials on the first loading platform or the second loading platform, and when the second loading platform moves to the second position, the first connection part still has a partial structure connected to the base to maintain the connection between the bracket and the base.

[0010] In some embodiments of the present application, the bracket further comprises a slide rail. The slide rail is disposed on the base. The first connecting portion is slidably disposed on the slide rail. The slide rail constrains the position of the first connecting portion in a direction perpendicular to the second direction to prevent the first connecting portion from disengaging from the slide rail in a direction perpendicular to the second direction.

[0011] In the above embodiment, by setting the slide rail, on the one hand, the stability of the lifting and sliding action of the bracket and the accuracy of the sliding direction are facilitated, and on the other hand, when the second loading platform moves to the second position, the possibility of the second loading platform gradually becoming suspended in the air compared to the base and the first loading platform and crushing the bracket is reduced.

[0012] In some embodiments of the present application, the bracket further comprises a baffle. The baffle is connected to the first connecting portion, the second connecting portion and the third connecting portion. Along the third direction, the baffle is located on a side of the first connecting portion, the second connecting portion and the third connecting portion away from the first loading platform and the second loading platform. The first direction and the second direction are respectively perpendicular to the third direction.

[0013] In the above embodiment, by setting the baffle, on the one hand, the connection strength between the first connecting part, the second connecting part and the third connecting part can be strengthened, thereby improving the supporting stability of the bracket for the second loading platform; on the other hand, it can block between the first loading platform and the second loading platform in a direction perpendicular to the third direction, which does not affect the sliding of the bracket and can also protect the materials or the structure of the material transport vehicle between the first loading platform and the second loading platform, thereby improving the safety of the material transport vehicle in transporting materials.

[0014] In some embodiments of the present application, the material transport vehicle further comprises a sliding drive assembly. The sliding drive assembly is disposed on the base. The sliding drive assembly is connected to the bracket. The sliding drive assembly is configured to drive the bracket to slide in the forward and reverse directions along the second direction.

[0015] In the above embodiment, the bracket is driven to slide by the sliding drive assembly, which facilitates the material transport vehicle to automatically transport materials and saves labor costs.

[0016] In some embodiments of the present application, the sliding drive assembly includes a sliding drive member, a gear and a rack. The sliding drive member is disposed on a base. The gear is rotatably disposed on the base. The sliding drive member is configured to drive the gear to rotate. The rack is disposed on a bracket. The rack is meshed with the gear.

[0017] In the above embodiment, the sliding drive member drives the bracket to slide through the transmission cooperation of the gear and the rack, which is conducive to improving the stability of the bracket sliding and facilitating the control of the sliding speed of the bracket. At the same time, compared with other transmission methods such as ball screw pairs that are also easy to control the speed, the gear and rack transmission cooperation occupies less space, which is conducive to reducing the obstruction to the work of other structures of the material transport vehicle and reducing the occupied space of the material transport vehicle.

[0018] In some embodiments of the present application, the material transport vehicle further comprises a mechanical arm. The mechanical arm is configured to grab and place materials on the first loading platform or the second loading platform. The mechanical arm is disposed on the base. The mechanical arm and the first loading platform are distributed along the second direction.

[0019] In the above embodiment, by setting a mechanical arm, it is convenient for the material transport vehicle to automatically transport materials. The mechanical arm and the first loading platform are distributed along the second direction. On the one hand, the mechanical arm will not hinder the second loading platform from moving to the second position; on the other hand, when the second loading platform moves to the second position, on the basis of the first loading platform occupying a certain position, the mechanical arm and the second loading platform only increase the occupied area of ​​the material transport vehicle along a single straight line direction parallel to the second direction, rather than increasing the occupied area of ​​the material transport vehicle along multiple straight lines or broken lines. This is beneficial in that when arranging or moving the material transport vehicle, only the occupied area of ​​the material transport vehicle needs to be considered in a single straight line direction, thereby facilitating the reduction of the overall occupied area of ​​the material transport vehicle during movement.

[0020] In some embodiments of the present application, the material transport vehicle further comprises a visual recognition device. The visual recognition device is configured to recognize materials located at the robotic arm. The visual recognition device is disposed on the base. Along the second direction, the visual recognition device is located between the base and the first loading platform, and between the base and the second loading platform.

[0021] In the above embodiment, by setting up a visual recognition device, it is convenient for the robot arm to accurately pick up and place materials. And the setting position of the visual recognition device is conducive to only considering the occupied area of ​​the material transport vehicle in a single straight line direction when arranging or moving the material transport vehicle, thereby helping to reduce the overall occupied area during the movement of the material transport vehicle. And the visual recognition device is set between the robot arm and the first loading platform, then when the second loading platform moves to the first position, the visual recognition device can be used to identify the position and posture of the material when the material is transferred between the second loading platform and the robot arm; when the second loading platform moves to the second position, the visual recognition device can be used to identify the position and posture of the material when the material is transferred between the first loading platform and the robot arm.

[0022] An embodiment of the present application provides an operation device. The operation device includes a frame and a material transport vehicle as described in any of the above embodiments. The frame is provided with an operation area. The operation area is configured to provide materials for production operations. There are multiple operation areas and they are distributed along the second direction. The material transport vehicle is located on one side of the multiple operation areas and is configured to move forward and backward along the second direction.

[0023] In the above embodiment, the moving direction of the material transport vehicle is parallel to the distribution direction of the multiple working areas, so that the material transport vehicle transfers materials to the multiple working areas. And the moving direction of the material transport vehicle is parallel to the sliding direction of the bracket, so when the second loading platform moves to the second position, the second loading platform increases the occupied area of ​​the material transport vehicle on the moving path of the material transport vehicle, and has no or little effect on the overall area covered by the movement of the material transport vehicle. From the overall point of view, it is conducive to reducing the area occupied by the material transport vehicle to transfer materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0057] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0058] Furthermore, the terms “first,” “second,” “third,” etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

[0059] The embodiment of the present application provides a material transport vehicle and an operating device. The material transport vehicle is used to transport materials. The material transport vehicle includes a base, a first loading platform, a bracket and a second loading platform. The first loading platform is configured to carry materials along a first direction. The first loading platform is arranged on the base. The bracket is arranged on the base. The bracket is configured to be able to slide in a positive and reverse direction relative to the first loading platform along a second direction. The second direction is perpendicular to the first direction. The second loading platform is configured to carry materials along the first direction. The second loading platform is arranged on the bracket and is spaced apart from the first loading platform along the first direction. The second loading platform is configured to be able to move to a first position and a second position. When the second loading platform moves to the first position, at least part of the projection of the second loading platform overlaps with the first loading platform in the opposite direction of the first direction. When the second loading platform moves to the second position, the area of ​​the projection of the second loading platform overlapping with the first loading platform in the opposite direction of the first direction is reduced compared to when it is in the first position.

[0060] The first loading platform and the second loading platform carry materials respectively and stack them to form different material piles, so that the material transport vehicle can transport materials before and after production operations at the same time. The distribution direction of the first loading platform and the second loading platform is parallel to the direction in which the materials are stacked on the two. When the second loading platform is in the first position, the area where it is located at least partially overlaps with the area where the first loading platform is located in the direction perpendicular to the direction of carrying materials. Then, the positions of materials in different material piles can at least partially overlap in the direction perpendicular to the stacking direction, so that the area occupied by the materials on the material transport vehicle is reduced, which is conducive to reducing the area occupied by the material transport vehicle, so as to expand the scale of material production operations. When the second loading platform is in the second position, the part of the area where it is located in the direction perpendicular to the direction of carrying materials and the area where the first loading platform is located is reduced, so that the second loading platform is staggered with the first loading platform in the direction perpendicular to the material stacking, so as to facilitate stacking materials on the first loading platform or taking materials out of the first loading platform. By setting up the bracket, the second loading platform can be placed in the first position so that the second loading platform and the first loading platform at least partially overlap in a direction perpendicular to the first direction, and the second loading platform can be moved to the second position to facilitate the loading and unloading of materials on the first loading platform, thereby improving the efficiency of the material transport vehicle in transferring materials while reducing the occupied area of ​​the material transport vehicle, thereby facilitating the expansion of the scale of material production operations.

[0061] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0062] See also Figure 1, an embodiment of the present application provides an operation device 200. The operation device 200 includes a frame 201 and a material transport vehicle 100. The frame 201 is provided with an operation area 2011. The operation area 2011 is configured to provide materials 300 for production operations. The material transport vehicle 100 is configured to transport materials 300. Specifically, the materials 300 before the production operation may be transferred from the material transport vehicle 100 to the operation area 2011 of the frame 201 for production operations, or the materials 300 after the production operation may be transferred from the operation area 2011 of the frame 201 to the material transport vehicle 100 for transportation.

[0063] See also Figure 1 In some embodiments, the material 300 is a PCB (Printed Circuit Board). The operation device 200 can perform production operations such as etching, welding, and mounting on the PCB. In other embodiments, the material 300 can be a plastic part, and the operation device 200 can perform production operations such as cutting, grinding, and drilling on the plastic part; or the material 300 can also be the raw materials, semi-finished products, and finished products of other products to be produced, and the operation device 200 is used to process and manufacture the products to be produced.

[0064] See also Figure 1 In some embodiments, the material 300 is stacked on the material transport vehicle 100 along the first direction Z and forms a material pile for easy transportation. The material transport vehicle 100 moves in the forward and reverse directions along the second direction Y to transfer the material 300 to different positions of the rack 201. The material transport vehicle 100 and the rack 201 are distributed along the third direction X, so that the material transport vehicle 100 can move beside one side of the rack 201. The first direction Z, the second direction Y and the third direction X are perpendicular to each other. The first direction Z is opposite to the direction of gravity. Among them, the definitions of "first direction Z", "second direction Y" and "third direction X" are for the convenience of describing the relative position relationship of related structures, and do not mean that "first direction Z", "second direction Y" and "third direction X" need to rely on the related structures involved in the above definitions.

[0065] See also Figure 1 In some embodiments, a plurality of working areas 2011 are provided and distributed along the second direction Y. The material transport vehicle 100 moves in the forward direction and the reverse direction along the second direction Y. The moving direction of the material transport vehicle 100 is parallel to the distribution direction of the plurality of working areas 2011 , so that the material transport vehicle 100 transfers the material 300 to the plurality of working areas 2011 .

[0066] See also Figure 2In some embodiments, the material transport vehicle 100 includes a base 10, a first loading platform 20, a bracket 30, and a second loading platform 40. The first loading platform 20 is disposed on the base 10. The first loading platform 20 is configured to carry material 300 along a first direction Z. The bracket 30 is disposed on the base 10, wherein the bracket 30 can be directly connected to the base 10, or indirectly connected to the base 10 through the first loading platform 20 or other structures. The second loading platform 40 is disposed on the bracket 30. The second loading platform 40 is configured to carry material 300 along the first direction Z.

[0067] The first loading platform 20 and the second loading platform 40 respectively carry materials 300 and stack them to form different piles, so that the material transport vehicle 100 can simultaneously transfer materials 300 before and after production operations, or simultaneously transfer multiple piles of materials 300 before production operations, or simultaneously transfer multiple piles of materials 300 after production operations, and the efficiency of transferring materials 300 is high.

[0068] See also Figure 2 and Figure 3 In some embodiments, the material transport vehicle 100 further includes a moving component 50. The moving component 50 is disposed on the base 10. The material transport vehicle 100 moves via the moving component 50.

[0069] See also Figure 1 and Figure 3 It is understood that in some embodiments, the moving assembly 50 includes a rolling member 51. The material transport vehicle 100 is moved by rolling the rolling member 51. For example, the rolling member 51 can be a wheel, a ball, a roller, a track, a belt, etc. In other embodiments, the moving assembly 50 includes a sliding member. The material transport vehicle 100 is moved by sliding the sliding member. For example, the sliding member can be a slider that slides along a track, etc.

[0070] See also Figure 1 and Figure 3 It is understood that in some embodiments, the moving assembly 50 further includes a moving driving member 52. The moving driving member 52 drives the rolling member 51 and / or the sliding member to move. For example, the driving moving member may be a cylinder, a motor, a hydraulic cylinder, etc. In other embodiments, the moving driving member 52 may be omitted, and the material transport vehicle 100 may be driven to move manually or by the related structures of the frame 201.

[0071] See also Figure 1 and Figure 2In some embodiments, the second loading platform 40 is spaced apart from the first loading platform 20 along the first direction Z. The bracket 30 is configured so that at least a portion of the structure can slide relative to the first loading platform 20 in the positive and reverse directions along the second direction Y. The second loading platform 40 is configured to be movable to a first position and a second position. When the second loading platform 40 moves to the first position, at least a portion of the projection of the second loading platform 40 overlaps with the first loading platform 20 in the reverse direction of the first direction Z. When the second loading platform 40 moves to the second position, the area where the projection of the second loading platform 40 overlaps with the first loading platform 20 in the reverse direction of the first direction Z is reduced compared to when it is in the first position. It can be understood that in some embodiments, under extreme working conditions, when the second loading platform 40 moves to the first position, the projection of the second loading platform 40 in the opposite direction of the first direction Z completely overlaps with the first loading platform 20; when the second loading platform 40 moves to the second position, the projection of the second loading platform 40 in the opposite direction of the first direction Z completely does not overlap with the first loading platform 20. In this application, Figure 2 and Figure 3 It is a schematic diagram of the structure when the second loading platform 40 moves to the first position, and omits the schematic diagram when the bracket 30 drives the second loading platform 40 to move to the second position.

[0072] The distribution directions of the first loading platform 20 and the second loading platform 40 are parallel to the direction in which the materials 300 are stacked on the two. When the second loading platform 40 is in the first position, the area where it is located at least partially overlaps with the area where the first loading platform 20 is located in the direction perpendicular to the direction of the material 300, so that the positions of the materials 300 of different piles can at least partially overlap in the direction perpendicular to the stacking, so that the area occupied by the material 300 on the material transport vehicle 100 is reduced, which is conducive to reducing the area occupied by the material transport vehicle 100, so as to expand the scale of the production operation of the material 300. When the second loading platform 40 is in the second position, the part of the area where it is located in the direction perpendicular to the direction of the material 300 is reduced, so that the second loading platform 40 is staggered with the first loading platform 20 in the direction perpendicular to the stacking of the material 300, so as to facilitate the stacking of the material 300 on the first loading platform 20 or the removal of the material 300 from the first loading platform 20. By setting the bracket 30, the second loading platform 40 can be placed in the first position so that the second loading platform 40 and the first loading platform 20 at least partially overlap in a direction perpendicular to the first direction Z, and the second loading platform 40 can be moved to the second position to facilitate the loading and unloading of materials 300 to the first loading platform 20, thereby improving the efficiency of the material transport vehicle 100 in transporting the material 300 while reducing the occupied area of ​​the material transport vehicle 100, thereby facilitating the expansion of the scale of material 300 production operations.

[0073] And the moving direction of the material transport vehicle 100 is parallel to the sliding direction of the bracket 30. Then, when the second loading platform 40 moves to the second position, the second loading platform 40 increases the occupied area of ​​the material transport vehicle 100 on the moving path of the material transport vehicle 100, and has no or little effect on the overall area covered by the movement of the material transport vehicle 100. From the overall point of view, it is beneficial to reduce the area occupied by the material transport vehicle 100 for transferring materials 300. If the sliding direction of the bracket 30 is perpendicular to or intersecting with the moving direction of the material transport vehicle 100, even if the second loading platform 40 is in the first position, it is still necessary to reserve space for the second loading platform 40 to move to the second position on the moving path of the material transport vehicle 100, thereby increasing the area occupied by the material transport vehicle 100 for transferring materials 300.

[0074] See also Figure 1 and Figure 2 In some embodiments, a plurality of racks 201 are provided. The plurality of racks 201 are spaced apart along the third direction X. A material transport vehicle 100 is provided on at least one side of each rack 201 in the positive direction and the reverse direction along the third direction X. The moving direction of the material transport vehicle 100 is parallel to the sliding direction of the bracket 30 and is perpendicular to the distribution of the plurality of racks 201. The bracket 30 can slide so that the first loading platform 20 and the second loading platform 40 can transfer the material 300 respectively.

[0075] See also Figure 2 and Figure 3 In some embodiments, the projection of the first loading platform 20 in the reverse direction of the first direction Z is located within the range of the base 10. The first loading platform 20 is located within the range of the base 10 perpendicular to the first direction Z, which is beneficial to reducing the occupied area of ​​the material transport vehicle 100. In other embodiments, the projection of the first loading platform 20 in the reverse direction of the first direction Z may partially exceed the range of the base 10.

[0076] See also Figure 2 and Figure 3 In some embodiments, when the second loading platform 40 moves to the first position, the projection of the second loading platform 40 in the reverse direction of the first direction Z is located within the range of the base 10. When the second loading platform 40 moves to the second position, the projection of the second loading platform 40 in the reverse direction of the first direction Z is at least partially located outside the range of the base 10. It can be understood that in some embodiments, under extreme working conditions, when the second loading platform 40 moves to the second position, the projection of the second loading platform 40 in the reverse direction of the first direction Z can be completely located outside the range of the base 10.

[0077] When the second loading platform 40 moves to the first position, the first loading platform 20 and the second loading platform 40 are both within the range of the base 10 perpendicular to the first direction Z, so as to plan the storage position and moving path of the material transport vehicle 100 according to the size of the occupied area of ​​the base 10, and to reduce the occupied area of ​​the material transport vehicle 100. When the second loading platform 40 moves to the second position, it can move out of the range of the base 10 perpendicular to the first direction Z, so as to be staggered with the first loading platform 20 perpendicular to the first direction Z, so as to take and put the material 300 to the first loading platform 20, thereby reducing the occupied area of ​​the base 10, and further reducing the occupied area of ​​the material transport vehicle 100.

[0078] In other embodiments, when the second loading platform 40 moves to the first position, a projection of the second loading platform 40 in the opposite direction of the first direction Z may be located outside the range of the base 10 .

[0079] See also Figure 2 and Figure 3 In some embodiments, the bracket 30 includes a first connection portion 31, a second connection portion 32, and a third connection portion 33. The first connection portion 31 is slidably connected to the base 10, wherein the first connection portion 31 can be directly slidably connected to the base 10, or can be slidably connected to the first loading platform 20 or other structures and indirectly slidably connected to the base 10. The second connection portion 32 is connected to the second loading platform 40. Along the second direction Y, the extension length of the first connection portion 31 is greater than the extension length of the second connection portion 32. The third connection portion 33 is connected to the first connection portion 31 and the second connection portion 32.

[0080] The third connection portion 33 connects the first connection portion 31 and the second connection portion 32, so that the second loading platform 40 can be arranged on the base 10. In the second direction Y, the first connection portion 31 is longer than the second connection portion 32, which can reduce the space occupied by the second connection portion 32 while maintaining the second loading platform 40 and the second connection portion 32, so as to facilitate the taking and placing of the material 300 on the first loading platform 20 or the second loading platform 40, and when the second loading platform 40 moves to the second position, the first connection portion 31 still has a partial structure connected to the base 10 to maintain the connection between the bracket 30 and the base 10.

[0081] In other embodiments, along the second direction Y, the extension length of the first connection portion 31 and the extension length of the second connection portion 32 may be equal, or the extension length of the first connection portion 31 may be greater than the extension length of the second connection portion 32 .

[0082] See also Figure 3In some embodiments, the third connection part 33 is rod-shaped. A plurality of third connection parts 33 are provided. The plurality of third connection parts 33 are distributed along the second direction Y to enhance the stability of the fixation between the first connection part 31 and the second connection part 32. It can be understood that in some embodiments, the extension direction of the third connection part 33 can be parallel to the first direction Z, or can intersect with the first direction Z; the extension directions of different third connection parts 33 can be different.

[0083] See also Figure 2 and Figure 3 In some embodiments, the bracket 30 further includes a slide rail 34. The slide rail 34 is disposed on the base 10, wherein the slide rail 34 may be directly connected to the base 10, or may be indirectly connected to the base 10 through the first loading platform 20 or other structures. The first connecting portion 31 is slidably disposed on the slide rail 34. The slide rail 34 constrains the position of the first connecting portion 31 in a direction perpendicular to the second direction Y to prevent the first connecting portion 31 from detaching from the slide rail 34 in a direction perpendicular to the second direction Y.

[0084] By setting the slide rail 34, on the one hand, it is convenient to facilitate the stability of the sliding action and the accuracy of the sliding direction of the bracket 30, and on the other hand, when the second loading platform 40 moves to the second position, it is reduced that the second loading platform 40 is gradually suspended compared with the base 10 and the first loading platform 20 and the possibility of overturning the bracket 30 is reduced.

[0085] In some embodiments, there are multiple slide rails 34, and the multiple slide rails 34 are distributed along the first direction Z (not shown). There are multiple first connecting parts 31, and each first connecting part 31 is slidably matched with a different slide rail 34. This improves the stability of the sliding action of the bracket 30 and the accuracy of the sliding direction, and further improves the stability of the support for the second loading platform 40.

[0086] See also Figure 2 and Figure 3 In some embodiments, the bracket 30 further includes a baffle 35. The baffle 35 is connected to the first connection portion 31, the second connection portion 32, and the third connection portion 33. Along the third direction X, the baffle 35 is located on a side of the first connection portion 31, the second connection portion 32, and the third connection portion 33 away from the first loading platform 20 and the second loading platform 40.

[0087] By setting the baffle 35, on the one hand, the connection strength between the first connecting part 31, the second connecting part 32 and the third connecting part 33 can be strengthened, thereby improving the supporting stability of the bracket 30 for the second loading platform 40; on the other hand, it can be blocked between the first loading platform 20 and the second loading platform 40 in a direction perpendicular to the third direction X, which does not affect the sliding of the bracket 30 and can also protect the material 300 or the structure of the material transport vehicle 100 located between the first loading platform 20 and the second loading platform 40, thereby improving the safety of the material transport vehicle 100 in transporting the material 300.

[0088] See also Figure 2 and Figure 3 In some embodiments, along the third direction X, brackets 30 are respectively provided on both sides of the first loading platform 20 and the second loading platform 40. Preferably, partial structures of the brackets 30 on both sides can be connected to each other to enhance the stability of supporting the second loading platform 40.

[0089] See also Figure 2 and Figure 3 In some embodiments, the material transport vehicle 100 further includes a sliding drive assembly 60. The sliding drive assembly 60 is disposed on the base 10, wherein the sliding drive assembly 60 can be directly connected to the base 10, or indirectly connected to the base 10 through the first loading platform 20 or other structures. The sliding drive assembly 60 is connected to the bracket 30. The sliding drive assembly 60 is configured to drive the bracket 30 to slide in the forward and reverse directions along the second direction Y.

[0090] The bracket 30 is driven to slide by the sliding drive assembly 60, so that the material transport vehicle 100 can automatically transport the material 300, saving labor costs.

[0091] See also Figures 2 to 4 In some embodiments, the sliding drive assembly 60 includes a sliding drive member (not shown), a gear 61 and a rack 62. The sliding drive member is disposed on the base 10. The gear 61 is rotatably disposed on the base 10. The sliding drive member or the gear 61 can be directly connected to the base 10, or can be indirectly connected to the base 10 through the first loading platform 20 or other structures. The sliding drive member is configured to drive the gear 61 to rotate. The rack 62 is disposed on the bracket 30. The rack 62 is meshed and connected with the gear 61. Specifically, the rack 62 is disposed on the first connecting portion 31.

[0092] Through the transmission cooperation of the gear 61 and the rack 62, the sliding drive member drives the bracket 30 to slide, which is conducive to improving the stability of the sliding of the bracket 30 and facilitating the control of the sliding speed of the bracket 30. At the same time, compared with other transmission methods such as ball screw pairs that are also easy to control the speed, the transmission cooperation of the gear 61 and the rack 62 occupies a smaller space, which is conducive to reducing the obstruction to the operation of other structures of the material transport vehicle 100 and reducing the occupied space of the material transport vehicle 100.

[0093] In other embodiments, the sliding drive assembly 60 can be controlled by a cylinder or the like.

[0094] See also Figure 2 and Figure 3In some embodiments, the material transport vehicle 100 further includes a robotic arm 70. The robotic arm 70 is configured to grab and release the material 300 to the first loading platform 20 or the second loading platform 40. The robotic arm 70 is disposed on the base 10, wherein the robotic arm 70 can be directly connected to the base 10, or indirectly connected to the base 10 through the first loading platform 20 or other structures. The robotic arm 70 and the first loading platform 20 are distributed along the second direction Y.

[0095] By setting the mechanical arm 70, it is convenient for the material transport vehicle 100 to automatically transport the material 300. The mechanical arm 70 and the first loading platform 20 are distributed along the second direction Y. On the one hand, the mechanical arm 70 will not hinder the second loading platform 40 from moving to the second position; on the other hand, when the second loading platform 40 moves to the second position, on the basis of the first loading platform 20 occupying a certain position, the mechanical arm 70 and the second loading platform 40 only increase the occupied area of ​​the material transport vehicle 100 along a single straight line direction parallel to the second direction Y, rather than increasing the occupied area of ​​the material transport vehicle 100 along multiple straight lines or folded lines. This is beneficial when arranging or moving the material transport vehicle 100, and only needs to consider the occupied area of ​​the material transport vehicle 100 in a single straight line direction, thereby helping to reduce the overall occupied area of ​​the material transport vehicle 100 during the movement process.

[0096] See also Figure 1 In some embodiments, the robot arm 70 is provided with a movable clamp to carry the material 300 by clamping. In other embodiments, the robot arm 70 is provided with a vacuum nozzle to carry the material 300 by adsorption. The robot arm 70 may also carry the material 300 in other ways, which is not limited in the present application.

[0097] See also Figure 2 and Figure 3 In some embodiments, the material transport vehicle 100 further includes a visual recognition device 80. The visual recognition device 80 is configured to identify the material 300 located at the robotic arm 70. The visual recognition device 80 is disposed on the base 10, wherein the visual recognition device 80 can be directly connected to the base 10, or indirectly connected to the base 10 through the first loading platform 20 or other structures. Along the second direction Y, the visual recognition device 80 is located between the base 10 and the first loading platform 20, and between the base 10 and the second loading platform 40. As an illustrative example, the visual recognition device 80 includes but is not limited to a CCD camera (CCD, charge coupled device).

[0098] By setting the visual recognition device 80, it is convenient for the mechanical arm 70 to accurately pick up and place the material 300. In addition, the setting position of the visual recognition device 80 is similar to the setting position of the mechanical arm 70, which is also beneficial to only consider the occupied area of ​​the material transport vehicle 100 in a single straight line direction when arranging or moving the material transport vehicle 100, thereby helping to reduce the overall occupied area of ​​the material transport vehicle 100 during the movement process. In addition, the visual recognition device 80 is set between the mechanical arm 70 and the first loading platform 20, so when the second loading platform 40 moves to the first position, the visual recognition device 80 can be used to identify the position and posture of the material 300 when the material 300 is transferred between the second loading platform 40 and the mechanical arm 70; when the second loading platform 40 moves to the second position, the visual recognition device 80 can be used to identify the position and posture of the material 300 when the material 300 is transferred between the first loading platform 20 and the mechanical arm 70.

[0099] See also Figure 1 and Figure 2 In some embodiments, the working principle of the material transport vehicle 100 and the operating device 200 is:

[0100] The materials 300 before the production operation are stacked on the second loading platform 40, and the second loading platform 40 is moved to the first position. The robot arm 70 transfers the materials 300 on the second loading platform 40 to the working area 2011 of the frame 201, and as the material transport vehicle 100 moves forward or backward along the second direction Y, the robot arm 70 transfers the materials 300 on the second loading platform 40 to different working areas 2011;

[0101] The second loading platform 40 moves to the second position, and the robot arm 70 stacks the materials 300 after the production operation in the working area 2011 on the first loading platform 20, and as the material transport vehicle 100 moves forward or reverse along the second direction Y, the robot arm 70 transfers the materials 300 in different working areas 2011 to the first loading platform 20.

[0102] In the present application, the relatively fixed arrangement of the two does not mean that they cannot be disassembled, but is intended to indicate that when the material transport vehicle 100 is in use, the relatively fixed two can move together.

[0103] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
