[0030] Reference below Figure 1-Figure 3 The pallet lifting mechanism 100 according to an embodiment of the present invention is described. By setting up a wire pallet 2, parts can be carried, and the transmission member 3 can drive the wire pallet 2 to rise and fall under the action of the driving member 4, so that the wire pallet 2 can drive the parts set thereon to rise and fall for assembly with other parts. The transmission member 3 is movable along a first direction, and the first direction intersects with the up and down direction. The transmission member 3 and the wire pallet 2 can be staggered and distributed along the up and down direction to reduce the setting length and occupied space of the pallet lifting mechanism 100 in the up and down direction, which is beneficial to the setting of the pallet lifting mechanism 100 and can help improve the stability of the operation of the pallet lifting mechanism 100.

[0031] like Figure 1 As shown, a pallet lifting mechanism 100 according to an embodiment of the present invention includes: a mounting base 1, a line pallet 2, a transmission member 3 and a driving member 4.

[0032] The wire tray 2 can be installed above the mounting base 1 in a liftable manner; the transmission member 3 can be movably installed on the mounting base 1 along a first direction, and the first direction intersects with the up and down directions; the driving member 4 is used to drive the transmission member 3 to move along the first direction, and the transmission member 3 drives the wire tray 2 to move up and down.

[0033] Specifically, the pallet lifting mechanism 100 is used to drive the lifting of parts to achieve assembly with other parts. The pallet lifting mechanism 100 includes a mounting base 1, a wire pallet 2, a transmission member 3 and a driving member 4, wherein the wire pallet 2 is used to carry parts. The wire pallet 2 can be constructed into a flat plate to increase the installation area of ​​the wire pallet 2, so that the wire pallet 2 can adapt to parts of different sizes, thereby increasing the scope of application of the pallet lifting mechanism 100. At the same time, the wire pallet 2 can be installed on the top of the mounting base 1 in a liftable manner, so as to achieve the installation of the wire pallet 2, and the wire pallet 2 can be lifted relative to the mounting base 1, thereby driving the parts arranged on the top of the wire pallet 2 to be lifted for assembly with other parts. Moreover, the wire pallet 2 is arranged above the mounting base 1 to avoid the mounting base 1 from blocking the wire pallet 2, thereby ensuring that the wire pallet 2 can drive the parts located thereon to be lifted.

[0034] In addition, the mounting base 1 is used to provide an installation position for the transmission member 3, and the transmission member 3 is used to drive the wire tray 2 to rise and fall. The transmission member 3 is movably installed on the mounting base 1 along a first direction, so that the installation of the transmission member 3 can be realized, and the transmission member 3 can be movable relative to the mounting base 1 along the first direction to drive the wire tray 2 to rise and fall while moving, wherein the first direction intersects with the up and down direction, that is, the movement direction of the transmission member 3 is different from the movement direction of the wire tray 2, and the first direction can be any direction except the up and down direction, such as the left and right direction or the front and back direction, and the transmission member 3 is movable along the first direction, so that the transmission member 3 and the wire tray 2 can be staggered in the up and down direction, so as to reduce the setting length and occupied space of the tray lifting mechanism 100 along the up and down direction, which is beneficial to the setting of the tray lifting mechanism 100 and can help to improve the stability of the operation of the tray lifting mechanism 100.

[0035] In addition, the driving member 4 is used to provide driving force, and the driving member 4 can be constructed as a driving motor, etc., so that the driving member 4 can drive the transmission member 3 to move in the first direction, that is, the driving member 4 can be connected to the transmission member 3, so that the driving member 4 can transmit the driving force to the transmission member 3, and then the transmission member 3 can move in the first direction under the action of the driving member 4, and the driving member 4 can make the transmission member 3 drive the wire tray 2 to rise and fall, that is, the transmission member 3 can be connected to the driving member 4 and the wire tray 2 at the same time, so that the transmission member 3 can drive the wire tray 2 to rise and fall under the action of the driving member 4, and then the wire tray 2 can drive the parts arranged thereon to rise and fall for assembly with other parts.

[0036] Therefore, the transmission member 3 can be installed by setting up the installation base 1, and the transmission member 3 is connected to the driving member 4 and the wire tray 2 at the same time, so that the transmission member 3 can drive the wire tray 2 to rise and fall under the drive of the driving member 4, and then the wire tray 2 can drive the parts arranged thereon to rise and fall so as to be assembled with other parts.

[0037] According to the pallet lifting mechanism 100 of the embodiment of the present invention, the parts can be carried by setting the wire pallet 2, and the transmission member 3 can drive the wire pallet 2 to rise and fall under the action of the driving member 4, so that the wire pallet 2 can drive the parts set thereon to rise and fall for assembly with other parts, and the transmission member 3 is movable along the first direction, and the first direction intersects with the up and down direction, so that the transmission member 3 and the wire pallet 2 can be staggered and distributed along the up and down direction to reduce the setting length and occupied space of the pallet lifting mechanism 100 in the up and down direction, which is beneficial to the setting of the pallet lifting mechanism 100 and can help to improve the stability of the operation of the pallet lifting mechanism 100.

[0038] In some embodiments, the first direction is along the horizontal direction, and the transmission member 3 is configured to be slidably installed above the mounting base 1 along the horizontal direction.

[0039] Specifically, the transmission member 3 is used to move along a first direction under the action of the driving member 4 to drive the wire tray 2 to rise and fall, and the first direction is along the horizontal direction, that is, the first direction can be any direction along the horizontal plane, such as the front-to-back direction or the left-to-right direction, so that the first direction intersects and is perpendicular to the up-down direction, which can effectively reduce the setting length and occupied space of the tray lifting mechanism 100 in the up-down direction, and the transmission member 3 is set to be slidably installed above the mounting base 1 along the horizontal direction, that is, the transmission member 3 and the wire tray 2 can be installed above the mounting base 1, so that the transmission member 3 can be close to the wire tray 2, so that the transmission member 3 can drive the wire tray 2 to rise and fall, and the transmission member 3 can slide in the horizontal direction relative to the mounting base 1, that is, the transmission member 3 can be slidably matched with the mounting base 1, so that the transmission member 3 can drive the wire tray 2 to rise and fall while sliding relative to the mounting base 1, and the sliding matching method is conducive to reducing the wear of the transmission member 3, and can extend the service life of the transmission member 3.

[0040] In such Figure 1 In the shown embodiment, a slide groove 13 extending in the left-right direction is provided on the mounting base 1, and the transmission member 3 is arranged on the slide groove 13 and slidably cooperates with the slide groove 13, so that the transmission member 3 can slide in the left-right direction relative to the mounting base 1 under the action of the driving member 4, that is, the first direction is the left-right direction, and the first direction intersects and is perpendicular to the up-down direction, which can effectively reduce the setting length and occupied space of the tray lifting mechanism 100 in the up-down direction, and the slide groove 13 can guide the movement of the transmission member 3 to improve the accuracy of the movement direction of the transmission member 3, and, in actual design, the extension direction of the slide groove 13 and the movement direction of the transmission member 3 can also be flexibly set according to actual conditions.

[0041] In some embodiments, at least a portion of the upper surface of the transmission member 3 is configured as a push slope 31 , and the push slope 31 is suitable for pushing the line tray 2 to rise and fall relative to the mounting base 1 during the movement of the transmission member 3 in the horizontal direction.

[0042] Specifically, the transmission member 3 can drive the wire tray 2 to rise and fall under the action of the driving member 4, and at least part of the upper surface of the transmission member 3 is constructed as a pushing slope 31, that is, part or all of the upper surface of the transmission member 3 can be constructed as a pushing slope 31, and the pushing slope 31 extends obliquely relative to the horizontal plane, that is, the pushing slope 31 has a certain height difference along the up and down directions. The transmission member 3 can be arranged below the wire tray 2, so that the pushing slope 31 is pressed and contacted with the bottom of the wire tray 2, so that when the transmission member 3 moves in the horizontal direction, the pushing slope 31 can push the wire tray 2 to rise and fall relative to the mounting base 1.

[0043] In some embodiments, the upper surface of the transmission member 3 further includes a first plane 32 and a second plane 33 , the pushing inclined plane 31 is connected between the first plane 32 and the second plane 33 , and the first plane 32 and the second plane 33 are both parallel to the horizontal plane.

[0044] Specifically, the upper surface of the transmission member 3 also includes a first plane 32 and a second plane 33, that is, part of the upper surface of the transmission member 3 can be constructed as a pushing inclined plane 31, so as to leave sufficient setting space for the first plane 32 and the second plane 33, and the pushing inclined plane 31 is connected between the first plane 32 and the second plane 33, that is, the first plane 32 and the second plane 33 are respectively connected to the two ends of the pushing inclined plane 31, and the first plane 32 and the second plane 33 are both parallel to the horizontal plane, that is, the first plane 32 and the second plane 33 extend in the horizontal direction, so that the first plane 32 and the second plane 33 have a certain height difference in the up and down directions.

[0045] Therefore, when the wire tray 2 moves along the pushing inclined plane 31, it can move to the first plane 32 or the second plane 33. At this time, the first plane 32 or the second plane 33 can be used to support the wire tray 2, so that the wire tray 2 can be stably maintained at this height position to improve the stability of the wire tray 2, which is beneficial to the assembly of components on the wire tray 2 with other components. The first plane 32 and the second plane 33 have a larger setting area, which can increase the contact area between the transmission member 3 and the wire tray 2, which is beneficial to improving the reliability of supporting the wire tray 2.

[0046] It should be noted that, for the convenience of description, the following description is based on an example in which the setting height of the first plane 32 is higher than the setting height of the second plane 33 .

[0047] In some embodiments, a first arc-shaped transition surface 34 is connected between the first plane 32 and the push slope 31 , and / or a second arc-shaped transition surface 35 is connected between the second plane 33 and the push slope 31 .

[0048] Specifically, the pushing slope 31 is connected to the first plane 32 and the second plane 33 at the same time, and a first arcuate transition surface 34 is connected between the first plane 32 and the pushing slope 31. The first arcuate transition surface 34 is used to connect the first plane 32 and the pushing slope 31, so as to form a smooth transition between the first plane 32 and the pushing slope 31, so that the line tray 2 can pass smoothly in the process of moving from the first plane 32 to the pushing slope 31, or from the pushing slope 31 to the first plane 32, which can improve the smoothness of the movement of the line tray 2 between the first plane 32 and the pushing slope 31, and avoid the occurrence of jamming and other situations that cause the line tray 2 to be unable to move, that is, cause the tray lifting mechanism 100 to fail.

[0049] At the same time, a second arc-shaped transition surface 35 is connected between the second plane 33 and the pushing inclined surface 31. The second arc-shaped transition surface 35 is used to connect the second plane 33 and the pushing inclined surface 31, so as to form a smooth transition between the second plane 33 and the pushing inclined surface 31, so that the line tray 2 can pass smoothly in the process of moving from the second plane 33 to the pushing inclined surface 31, or from the pushing inclined surface 31 to the second plane 33, which can improve the smoothness of the movement of the line tray 2 between the second plane 33 and the pushing inclined surface 31, and avoid the occurrence of jamming and other situations that cause the line tray 2 to be unable to move, that is, cause the failure of the tray lifting mechanism 100.

[0050] In some embodiments, a support roller 21 is provided at the bottom of the wire tray 2 , and the support roller 21 is rollingly supported on a pushing inclined surface 31 , and the pushing inclined surface 31 is suitable for pushing the support roller 21 to drive the wire tray 2 to move up and down.

[0051] Specifically, Figure 1-Figure 3 As shown, the wire tray 2 is supported above the transmission member 3, so that the transmission member 3 can push the wire tray 2 to rise and fall while moving along the first direction relative to the mounting base 1, and a supporting roller 21 is provided at the bottom of the wire tray 2, and the supporting roller 21 can be rotatably supported on the pushing inclined surface 31, that is, the supporting roller 21 can roll with the pushing inclined surface 31, so that when the transmission member 3 moves relative to the mounting base 1, the pushing inclined surface 31 can push the supporting roller 21 to roll along the pushing inclined surface 31, and then the supporting roller 21 can drive the wire tray 2 to rise and fall, and the rolling cooperation method can reduce the friction between the pushing inclined surface 31 and the supporting roller 21, which is beneficial to reduce the wear of the transmission member 3 and the supporting roller 21, and can extend the service life of the two.

[0052] In some embodiments, the pallet lifting mechanism 100 further includes a linkage structure 5 , there are multiple transmission members 3 , the multiple transmission members 3 are relatively fixed through the linkage structure 5 , and the driving member 4 is connected to the linkage structure 5 and / or one of the multiple transmission members 3 .

[0053] Specifically, the transmission member 3 is supported on the bottom of the wire tray 2 and is used to push the wire tray 2 up and down. The transmission member 3 can be set to be multiple, that is, the number of transmission members 3 can be two, three or more, so that the wire tray 2 can be jointly supported and pushed up and down by multiple transmission members 3, which can improve the reliability of the movement of the wire tray 2, and the multiple transmission members 3 can be distributed at intervals so that the multiple transmission members 3 can push the wire tray 2 to move at multiple positions at the same time, which can improve the stability of the movement of the wire tray 2, and the multiple transmission members 3 can be relatively fixed through the linkage structure 5, that is, the multiple transmission members 3 can be fixedly connected to the linkage structure 5 through connecting members or other methods, so that the multiple transmission members 3 can move synchronously under the action of the driving member 4, and then the multiple transmission members 3 can synchronously drive the wire tray 2 to rise and fall, so as to further improve the stability of the movement of the wire tray 2.

[0054] In addition, the driving member 4 is connected to the linkage structure 5 so that the driving member 4 can drive the linkage structure 5 to drive multiple transmission members 3 to move synchronously, or the driving member 4 is connected to one of the multiple transmission members 3 so that the driving member 4 can drive one of the transmission members 3 to drive other transmission members 3 to move together under the action of the linkage structure 5. Both of these can realize the synchronous movement of multiple transmission members 3, enable multiple transmission members 3 to jointly drive the line tray 2 to rise and fall, and can reduce the number of driving members 4 set, thereby reducing the setting cost.

[0055] In such Figure 1-Figure 3 In the illustrated embodiment, four transmission members 3 are provided, and the four transmission members 3 are divided into two groups along the front-to-back direction, and the two transmission members 3 in each group are spaced apart and distributed along the left-to-right direction, so that the linkage structure 5 can be constructed into a flat plate shape, and the four transmission members 3 are respectively provided at the four corners of the linkage structure 5, and the four transmission members 3 are relatively fixed by the linkage structure 5, so that the four transmission members 3 can move synchronously under the action of the linkage structure 5, and the middle part of the linkage structure 5 is hollowed out to form an avoidance space 51, and the avoidance space 51 is used to avoid the installation position of the driving member 4, that is, the driving member 4 can be provided in the avoidance space 51 and connected to the mounting base 1 to realize the installation of the driving member 4, and it can also be beneficial to reduce the space occupied by the tray lifting mechanism 100 in the horizontal direction, which is beneficial to the setting of the tray lifting mechanism 100.

[0056] Among them, it should be noted that a support roller 21 is provided at the bottom of the wire tray 2, and the support roller 21 rolls with the transmission member 3. The support roller 21 can also be set to four, so that the four support rollers 21 and the four transmission members 3 can be matched one by one, so as to improve the reliability and stability of the transmission member 3 pushing the support roller 21 to drive the wire tray 2 to rise and fall, and the number of transmission members 3 and support rollers 21 is not limited to that described in this embodiment, and can be flexibly set according to specific circumstances and space size.

[0057] In some embodiments, the driving member 4 is constructed as a driving cylinder, the piston rod 41 of the driving cylinder is connected to the linkage structure 5; and / or, the mounting base 1 is provided with two limit members 11 spaced apart along the first direction, the linkage structure 5 is located between the two limit members 11, and the linkage structure 5 is suitable for pressing against the limit member 11 when moving to the maximum position along the first direction.

[0058] Specifically, the driving member 4 is used to drive the transmission member 3 to move. The driving member 4 is constructed as a driving cylinder, and the piston rod 41 of the driving cylinder is connected to the linkage structure 5, so that the piston rod 41 can drive the linkage structure 5 to move when it is extended or retracted relative to the driving cylinder, so that the driving cylinder can drive the linkage structure 5 to move through the piston rod 41, and the four transmission members 3 relatively fixed to the linkage structure 5 can be driven to move synchronously, and then the driving cylinder can drive the linkage structure 5 to drive the four transmission members 3 to move synchronously, so as to improve the stability of the lifting and lowering of the line tray 2.

[0059] In addition, a limiting member 11 is provided on the mounting base 1. The limiting member 11 is used to limit the moving position of the linkage structure 5. The limiting member 11 is constructed into two, and the two limiting members 11 are spaced apart along the first direction and arranged on both sides of the linkage structure 5, so that the limiting member 11 can limit the two maximum positions of the linkage structure 5 moving along the first direction, that is, the linkage structure 5 can be pressed against the limiting member 11 when it moves to the maximum position along the first direction, so as to avoid the support roller 21 falling off from the transmission member 3 due to the long movement distance of the transmission member 3, thereby causing the tray lifting mechanism 100 to fail.

[0060] In some embodiments, a telescopic structure 12 is provided between the line tray 2 and the mounting base 1; wherein the telescopic structure 12 includes a telescopic sleeve 121 and a telescopic rod 122, the telescopic rod 122 is telescopically connected to the telescopic sleeve 121, one of the telescopic sleeve 121 and the telescopic rod 122 is connected to the line tray 2 and the other is connected to the mounting base 1.

[0061] Specifically, the telescopic structure 12 can be extended and retracted to change its own length. The telescopic structure 12 is set between the wire tray 2 and the mounting base 1, and the telescopic structure 12 can be connected to the wire tray 2 and the mounting base 1 at the same time, so that the telescopic structure 12 can be supported between the wire tray 2 and the mounting base 1 in the up and down directions to support the wire tray 2 and ensure that the wire tray 2 can remain stable after lifting and lowering. The wire tray 2 is connected to the mounting base 1 through the telescopic structure 12, and the telescopic structure 12 can be used to limit the movement direction of the wire tray 2 to prevent the wire tray 2 from moving along the first direction driven by the transmission member 3, thereby ensuring the accuracy of the movement direction of the wire tray 2.

[0062] At the same time, the telescopic structure 12 includes a telescopic sleeve 121 and a telescopic rod 122. The telescopic rod 122 is telescopically connected to the telescopic sleeve 121, so that the telescopic rod 122 can be extended and retracted relative to the telescopic sleeve 121 to change the length of the telescopic structure 12, so that the telescopic structure 12 can adapt to the setting height of the wire tray 2, that is, no matter to which height the wire tray 2 is raised or lowered, the telescopic structure 12 can reliably support the wire tray 2.

[0063] Furthermore, the telescopic sleeve 121 can be connected to the wire tray 2, and the telescopic rod 122 can be connected to the mounting base 1, or the telescopic rod 122 can be connected to the wire tray 2, and the telescopic sleeve 121 can be connected to the mounting base 1, so as to realize the connection between the telescopic structure 12 and the wire tray 2 and the mounting base 1, so that the wire tray 2 can drive the telescopic structure 12 to extend and retract when it is raised or lowered, and the telescopic structure 12 can reliably support the wire tray 2 and limit the movement of the wire tray 2 along the first direction.

[0064] For example, Figure 1-Figure 3 As shown, the telescopic sleeve 121 is connected to the mounting base 1, and the telescopic rod 122 is connected to the wire tray 2. When the wire tray 2 is lifted or lowered under the push of the transmission member 3, the telescopic rod 122 can be driven to extend or retract, and the telescopic structure 12 can support the wire tray 2 and limit the movement direction of the wire tray 2 to improve the reliability of the lifting and lowering of the wire tray 2.

[0065] In some embodiments, there are multiple telescopic structures 12 , and the multiple telescopic structures 12 are spaced apart and distributed on both sides of the transmission member 3 .
