[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0029] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] refer to Figures 1 to 8 The embodiment of the present application discloses a material transfer device for transferring a workpiece so as to place the workpiece in a box. The disclosed material transfer device includes a base frame 100 , a clamping mechanism 200 and a propping mechanism 300 .

[0031] The base frame 100 is a basic component, which can provide an installation foundation for the clamping mechanism 200, the opening mechanism 300, etc. In some embodiments, the clamping mechanism 200 and the opening mechanism 300 are both arranged on the base frame 100; the clamping mechanism 200 is used to clamp the workpiece, and the opening mechanism 300 is used to open the opening of the box containing the workpiece, so as to facilitate the placement of the workpiece in the box.

[0032] refer to Figure 4 , Figure 5 and Figure 7 The clamping mechanism 200 includes a first clamping jaw 211 and a second clamping jaw 212 which can be relatively close to or relatively far away from each other in a first direction, and a clamping space for accommodating a workpiece is provided between the first clamping jaw 211 and the second clamping jaw 212. Thus, when the workpiece needs to be clamped, the workpiece can be located in the clamping space and the first clamping jaw 211 and the second clamping jaw 212 can be relatively close to each other, so that the workpiece can be clamped from both sides of the workpiece in the first direction.

[0033] It should be noted that the first clamping jaw 211 and the second clamping jaw 212 may be relatively close to or relatively far away from each other in the first direction in the following ways: the first clamping jaw 211 moves toward or away from the second clamping jaw 212, or the second clamping jaw 212 moves toward or away from the first clamping jaw 211, or the first clamping jaw 211 and the second clamping jaw 212 move toward or away from each other. Of course, part or all of the first clamping jaw 211 may move in the first direction; part or all of the second clamping jaw 212 may move in the first direction, as long as the workpiece can be clamped or released, and the specific form is not limited.

[0034] refer to Figure 7 The opening mechanism 300 includes a first support member 311 and a second support member 312 that can be relatively close to or relatively far away from each other in the second direction, and the first support member 311 and the second support member 312 are located on both sides of the clamping space in the second direction, and are used to open the opening of the box body for placing the workpiece. Based on this, before placing the workpiece in the box body, the opening of the box body can be opened by moving the first support member 311 and the second support member 312 away from each other to facilitate the placement of the workpiece.

[0035] It should be noted here that, in the initial state, the box body can have a smaller opening so that the first support member 311 and the second support member 312, which are in a relatively close state, can extend into the opening; then, the first support member 311 and the second support member 312 are relatively far away from each other, and the first support member 311 pushes one side wall of the opening, and the second support member 312 pushes the other side wall of the opening, so that the two opposite side walls of the opening can be separated from each other, achieving a widening effect, thereby providing a sufficiently large space for the placement of the workpiece.

[0036] In addition, the first support member 311 and the second support member 312 may be relatively close to or relatively far away from each other in the second direction, including: the first support member 311 moves toward or away from the second support member 312, or the second support member 312 moves toward or away from the first support member 311, or the first support member 311 and the second support member 312 move closer to or away from each other. Of course, part or all of the first support member 311 may move in the second direction; part or all of the second support member 312 may move in the second direction.

[0037] In the embodiment of the present application, the workpiece to be packed can be clamped by the clamping mechanism 200 to ensure the stability of the workpiece during the packing process, prevent the workpiece from moving at will, and ensure the position accuracy of the workpiece; the opening of the box can be opened by the propping mechanism 300 before the workpiece is packed, so that the workpiece will not touch the opening of the box during the packing process, effectively preventing the workpiece from being stuck by the opening during the packing process, thereby ensuring that the workpiece can be smoothly placed in the box; in addition, the use of a material transfer device can replace manual labor to place the workpiece in the box, thereby reducing labor, improving loading efficiency, and ultimately improving material transfer efficiency.

[0038] To achieve the relative movement between the first support member 311 and the second support member 312, the spreading mechanism 300 may further include a first driving assembly 320, such as Figure 3 As shown, the first drive assembly 320 is arranged on the base frame 100, and the first drive assembly 320 is respectively connected to the first support member 311 and the second support member 312 in a transmission manner to respectively drive the first support member 311 and the second support member 312 to move in the second direction, so as to achieve the relative approach or relative distance between the two. Based on this arrangement, the common effect of the first drive assembly 320 can be achieved, which can ensure the driving of the first support member 311 and the second support member 312, ensure the synchronization of the movement of the two, and reduce the use of parts, so as to reduce the complexity of the device and reduce the cost while ensuring the synchronous movement of the first support member 311 and the second support member 312.

[0039] In addition, the first support member 311 and the second support member 312 can be movably connected to the base frame 100 to ensure that the first support member 311 and the second support member 312 can be relatively close to or relatively far away from each other in the second direction. The movable connection mode may include a sliding mode, a rotating mode, etc. When the movable mode is a sliding mode, the entire first support member 311 and the entire second support member 312 can be relatively close to or relatively far away from each other in the second direction; when the movable mode is a rotating mode, a part of the first support member 311 and a part of the second support member 312 can be relatively close to or relatively far away from each other in the second direction.

[0040] refer to Figures 3 to 5In some embodiments, the first driving assembly 320 may include a linear driving component 321, a transmission component 322, a first connecting component 323, and a second connecting component 324. The linear driving component 321 is connected to the transmission component 322, and drives the transmission component 322 to move in the third direction. The first connecting component 323 and the second connecting component 324 are respectively connected to the transmission component 322, and the first connecting component 323 is connected to the first support component 311, and the second connecting component 324 is connected to the second support component 312. In this way, the linear driving component 321 can drive the first connecting component 323 and the second connecting component 324 to move respectively through the transmission component 322, and drive the first support component 311 to move through the first connecting component 323, and drive the second support component 312 to move through the second connecting component 324, so as to achieve the relative approach or relative distance between the first support component 311 and the second support component 312.

[0041] For example, Figure 6 As shown, the linear drive component 321 may include a motor 3211, a screw rod 3212, and a moving member 3213. The rotating shaft of the motor 3211 is in transmission connection with the screw rod 3212, the moving member 3213 is threadedly connected with the screw rod 3212, and the transmission member 322 is connected with the moving member 3213, so that the motor 3211 drives the screw rod 3212 to rotate, the screw rod 3212 drives the moving member 3213 to move, and finally the moving member 3213 drives the transmission member 322 to move.

[0042] The first direction, the second direction and the third direction are perpendicular to each other. For example, in actual material conveying conditions, the first direction may be the front-to-back direction, the second direction may be the left-to-right direction, and the third direction may be the up-down direction.

[0043] Furthermore, if Figure 6 and Figure 7As shown, the transmission member 322 can be provided with a first guide groove 3221 and a second guide groove 3222, one end of the first connecting member 323 is slidably and rotatably connected to the first guide groove 3221, the other end of the first connecting member 323 is connected to the first support member 311, one end of the second connecting member 324 is slidably and rotatably connected to the second guide groove 3222, and the other end of the second connecting member 324 is connected to the second support member 312. Based on this, under the driving action of the linear driving component 321, the transmission member 322 can move along the third direction. At this time, the side wall of the first guide groove 3221 can generate a force on the first connecting member 323, thereby transmitting power and motion to the first support member 311 through the first connecting member 323, so that the first support member 311 moves. The side wall of the second guide groove 3222 can generate a force on the second connecting member 324, thereby transmitting power and motion to the second support member 312 through the second connecting member 324, so that the second support member 312 moves, and finally the first support member 311 and the second support member 312 can be made relatively close or relatively far away.

[0044] In some embodiments, the first support member 311 and the second support member 312 are spaced apart in the second direction, and both are rotatably connected to the base frame 100, so that under the action of the first connecting member 323 and the second connecting member 324, the first support member 311 and the second support member 312 can both rotate relative to the base frame 100, so that a part of the first support member 311 and a part of the second support member 312 are relatively close to or relatively far away from each other in the second direction.

[0045] Of course, in other embodiments, the first support member 311 and the second support member 312 may also be slidably connected to the base frame 100 respectively, so that all of the first support members 311 and all of the second support members 312 are relatively close to or relatively far away from each other in the second direction.

[0046] Furthermore, the first support member 311 is connected to the first connecting member 323, and the second support member 312 is connected to the second connecting member 324. In this way, the first connecting member 323 can drive the first support member 311 to rotate relative to the base frame 100, and the second connecting member 324 can drive the second support member 312 to rotate relative to the base frame 100.

[0047] In a more specific embodiment, the other end of the first connecting member 323 can be rotatably connected to the base frame 100 and serve as a rotation axis for the first supporting member 311 to rotate relative to the base frame 100; the other end of the second connecting member 324 can be rotatably connected to the base frame 100 and serve as a rotation axis for the second supporting member 312 to rotate relative to the base frame 100. Based on this configuration, there is no need to separately set up a rotation axis, which is conducive to reducing parts and reducing structural complexity.

[0048] In order to drive the first connecting member 323 respectively through the transmission member 322, the first guide groove 3221 and the second guide groove 3222 can be spaced apart in the second direction, and the first guide groove 3221 can extend along the third direction and obliquely toward the second guide groove 3222. In this way, during the movement of the transmission member 322 along the third direction, one end of the first connecting member 323 can be squeezed by the side wall of the first guide groove 3221, so that the first connecting member 323 can move (e.g., rotate) relative to the base frame 100, and the movement of the first connecting member 323 can drive the first support member 311 to move.

[0049] Similarly, in order to drive the second connecting member 324 respectively through the transmission member 322, the first guide groove 3221 and the second guide groove 3222 can be spaced apart in the second direction, and the second guide groove 3222 can extend along the third direction and obliquely toward the direction of the first guide groove 3221. In this way, during the movement of the transmission member 322 along the third direction, one end of the second connecting member 324 can be squeezed by the side wall of the second guide groove 3222, so that the second connecting member 324 can move (e.g., rotate) relative to the base frame 100, and the movement of the second connecting member 324 can drive the second support member 312 to move.

[0050] Exemplarily, the first guide groove 3221 can be a long groove set at an angle, and the second guide groove 3222 can also be a long groove set at an angle, and the first guide groove 3221 and the second guide groove 3222 can be symmetrically arranged in the second direction to ensure that the movement form of the first connecting member 323 and the second connecting member 324 are the same, and then ensure that the movement form of the first support member 311 and the second support member 312 are the same, so as to prevent the opening of the box from being skewed due to the different movement forms of the first support member 311 and the second support member 312, thereby ensuring the accuracy of the relative position between the opening of the box and the workpiece.

[0051] refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, in some embodiments, the base frame 100 may include a housing 110 and a mounting seat 120, wherein one end of the housing 110 along the third direction may be through, the mounting seat 120 is disposed in the housing 110, and the first support member 311 and the second support member 312 are respectively movably connected to one end of the housing 110 and are spaced apart in the second direction, and the first clamping jaw 211 and the second clamping jaw 212 are respectively movably connected to the mounting seat 120. Based on this arrangement, the first clamping jaw 211 and the second clamping jaw 212 can be installed through the mounting seat 120, and it is ensured that the first clamping jaw 211 and the second clamping jaw 212 can be relatively close to or relatively far away in the first direction, thereby achieving the clamping of the workpiece; the first support member 311 and the second support member 312 can be installed through the housing 110, and it is ensured that the first support member 311 and the second support member 312 can be relatively close to or relatively far away in the second direction, thereby achieving the expansion effect of the opening of the box. In addition, one end of the cover shell 110 along the third direction is designed to be through-type, which can ensure that the workpiece can enter the box body from one end of the cover shell 110.

[0052] In other embodiments, the first clamp 211 and the second clamp 212 can be movably connected to one end of the cover 110, and can be spaced apart in the first direction. The first support member 311 and the second support member 312 can be movably connected to one end of the cover 110, respectively. In this case, there is no need to set up the mounting base 120, which can reduce the structural complexity to a certain extent.

[0053] To realize the movement of the first clamping jaw 211 and the second clamping jaw 212, the clamping mechanism 200 may further include a second driving assembly 220 and a third driving assembly 230 respectively disposed on the mounting seat 120. Figure 8 As shown, the second driving assembly 220 can be connected to the first clamping jaw 211 to drive the first clamping jaw 211 to move relative to the mounting base 120, and the third driving assembly 230 can be connected to the second clamping jaw 212 to drive the second clamping jaw 212 to move relative to the mounting base 120.

[0054] In some embodiments, the second drive component 220 may include a first rack 221 extending along the second direction, and the first rack 221 is connected to the first clamp 211. The third drive component 230 may include a second rack 231 extending along the second direction, and the second rack 231 is connected to the second clamp 212. In this way, the first clamp 211 can be driven to move by the first rack 221, and the second clamp 212 can be driven to move by the second rack 231, thereby achieving the relative proximity or relative distance between the first clamp 211 and the second clamp 212 in the first direction.

[0055] In order to further improve the synchronization of movement between the first clamping jaw 211 and the second clamping jaw 212, a synchronization gear 240 can be connected between the first rack 221 and the second rack 231. Specifically, the synchronization gear 240 is respectively meshed with the first rack 221 and the second rack 231. In this way, the synchronization of movement of the first rack 221 and the second rack 231 can be ensured, and then the synchronization of movement of the first clamping jaw 211 and the second clamping jaw 212 can be achieved. Therefore, it can be ensured that the first clamping jaw 211 and the second clamping jaw 212 will not cause the workpiece to shift when clamping the workpiece, thereby ensuring the positioning accuracy of the workpiece.

[0056] In addition, the second drive assembly 220 and the second drive assembly 220 may also include a linear module to drive the first rack 221 and the second rack 231 to move along the third direction respectively through the linear module. For example, the linear module may be in the form of a cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0057] refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the material transfer device may further include a base 400, which may be a connecting member between the material transfer device and other devices. For example, the material transfer device may be mounted to a manipulator via the base 400, so that the material transfer device may be driven to move by the manipulator.

[0058] In order to realize the lifting of the workpiece, the material transfer device may further include a first lifting mechanism 500, such as Figure 1 , Figure 3 and Figure 5 As shown, the first lifting mechanism 500 is connected to the base 400, and the lifting end of the first lifting mechanism 500 is connected to the mounting seat 120 to drive the mounting seat 120 to move along the third direction. In this way, under the driving action of the first lifting mechanism 500, the mounting seat 120 can drive the workpiece clamped by the first clamp 211 and the second clamp 212 to be lifted and lowered along the third direction, thereby changing the position of the workpiece so as to facilitate the workpiece to enter the box.

[0059] Exemplarily, the first lifting mechanism 500 may include a linear module, which may be in the form of a cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0060] In order to move the first support member 311 and the second support member 312 of the opening mechanism 300 to the opening of the box body, the material conveying device may further include a second lifting mechanism 600, such as Figure 1 , Figure 2 and Figure 4As shown, the second lifting mechanism 600 is connected to the base 400, and the lifting end of the second lifting mechanism 600 is connected to the base frame 100 to drive the base frame 100 to move along the third direction. Based on this configuration, under the driving action of the second lifting mechanism 600, the base frame 100 can be lifted and lowered along the third direction, so that the first support member 311 and the second support member 312 connected to the base frame 100 can be lifted and lowered, so that the first support member 311 and the second support member 312 can be close to or away from the opening of the box.

[0061] Exemplarily, the second lifting mechanism 600 may include a linear module, which may be in the form of a cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0062] In order to improve the efficiency of placing the workpiece in the box, the material transfer device may include a plurality of second lifting mechanisms 600 and a plurality of base frames 100, such as Figure 1 The plurality of second lifting mechanisms 600 are respectively connected to the base 400 , and the lifting ends of the plurality of second lifting mechanisms 600 are respectively connected to the plurality of base frames 100 to respectively drive the plurality of base frames 100 to rise and fall along the third direction.

[0063] In addition, each base frame 100 is provided with a clamping mechanism 200 and an opening mechanism 300, so that multiple workpieces can be clamped by multiple clamping mechanisms 200, and multiple box openings can be opened by multiple opening mechanisms 300, so that multiple workpieces can be placed in multiple boxes respectively, thereby improving the packing efficiency of the workpieces.

[0064] To sum up, the material transfer device in the embodiment of the present application can effectively prevent the opening of the box from getting stuck with the workpiece, ensure that the workpiece can be smoothly placed in the box, and can replace manual methods, thereby reducing labor, improving loading efficiency, and ultimately improving material transfer efficiency.

[0065] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
