[0039] Reference below Figure 1-Figure 6 A platen pick-and-place device 500 according to an embodiment of the present invention is described.

[0040] Reference Figure 2 , Figure 4 and Figure 5 The platen pick-up and placement device 500 according to the embodiment of the present invention is used for picking up and placing the platen 600, and the platen 600 is provided with a first positioning member 610 protruding upward. The platen pick-up and placement device 500 includes: a truss 510, a lifting assembly 520, a stop plate 530 and a first locking assembly 540, wherein the truss 510 includes a mounting portion 511 and a support portion 512, and the support portion 512 supports the mounting portion 511; the lifting assembly 520 is arranged on the mounting portion 511, and the lifting assembly 520 includes a first driving assembly 521 and a lifting column 522, and the first driving assembly 521 is used to drive the lifting column 522 to move in the up and down direction; the stop plate 530 is arranged at the bottom end of the lifting column 522, and is used to stop with the platen 600; the first locking assembly 540 is arranged on the stop plate 530, and the first locking assembly 540 is used to lock and unlock the first positioning member 610.

[0041] Reference Figure 1 and Figure 2 In the above technical solution, the support portion 512 supports the mounting portion 511 so that there is a certain distance between the mounting portion 511 and the ground, and a space for placing the battery tray is formed below the mounting portion 511.

[0042] Reference Figure 1 , Figure 2 and Figure 5In some application scenarios, a fixture 2000 is provided below the mounting portion 511, the battery tray is placed on the fixture 2000, and a pressing plate 600 is placed on the upper side of the battery tray. After the battery tray is welded, the pressing plate 600 on the battery tray needs to be removed, the first driving assembly 521 drives the lifting column 522 to descend, and the stop plate 530 at the bottom of the lifting column 522 descends together with the lifting column 522. As the stop plate 530 continues to descend, the stop plate 530 abuts against the pressing plate 600, and then the first locking assembly 540 locks the first positioning member 610, thereby positioning the pressing plate 600 on the stop plate 530, and then the first driving assembly 521 drives the lifting column 522 to rise, and the pressing plate 600 rises together with the lifting column 522 to move away from the battery tray.

[0043] After the battery tray to be welded is placed on the fixture 2000, the pressing plate 600 needs to be placed on the battery tray, and the first driving component 521 drives the lifting column 522 to descend, and the pressing plate 600 positioned on the stop plate 530 descends together with the lifting column 522. After the pressing plate 600 descends to contact the battery tray, the first locking component 540 unlocks the first positioning member 610, and then the first driving component 521 drives the lifting column 522 to rise, and the stop plate 530 rises together with the lifting column 522. Because the restriction on the first positioning member 610 has been released, when the stop plate 530 rises, the pressing plate 600 stays on the battery tray, and the stop plate 530 rises until it is far away from the pressing plate 600 to facilitate subsequent welding operations.

[0044] According to the pressure plate picking and placing device 500 of the embodiment of the present invention, the pressure plate 600 can be automatically picked up and placed, and the staff does not need to use a forklift to carry the pressure plate 600, thereby improving the efficiency of picking up and placing the pressure plate 600 and improving the processing efficiency of the battery tray; during the process of picking up and placing the pressure plate 600, the pressure plate 600 moves along a fixed path with the lifting column 522, so that the pressure plate picking and placing device 500 can place the pressure plate 600 at a preset position each time it places the pressure plate 600, thereby improving the position accuracy of the pressure plate 600 when it cooperates with the battery tray; when the pressure plate picking and placing device 500 positions the pressure plate 600, the stop plate 530 stops with the pressure plate 600, thereby avoiding the possibility of shaking of the pressure plate 600, improving the stability of the pressure plate 600, and improving the safety of using the pressure plate picking and placing device 500.

[0045] In some embodiments, the stop plate 530 is provided with a first through hole 531 for the first positioning member 610 to pass through, and the first locking assembly 540 is located on the upper side of the stop plate 530. When the first locking assembly 540 locks the first positioning member 610, it restricts the first positioning member 610 from being separated from the first through hole 531, further improving the stability of the pressure plate picking and placing device 500 in grasping the pressure plate 600.

[0046] In some specific embodiments, the support portion 512 includes a plurality of support columns, which are arranged at intervals and jointly support the mounting portion 511, thereby improving the stability of the mounting portion 511. The mounting portion 511 is formed as a mounting platform, and a space is formed on the mounting platform for the convenience of the staff to move around, thereby improving the convenience of maintenance of the platen pick-up and placement device 500.

[0047] In some further embodiments, the truss 510 further includes a ladder 513 , which extends from the installation platform to the ground to facilitate workers to climb to the installation platform.

[0048] In some further embodiments, the truss 510 further includes a fence 514 disposed on the periphery of the installation platform to reduce the risk of workers slipping and falling, thereby improving the safety of the pressure plate picking and placing device 500.

[0049] Reference Figure 2 and Figure 3 In some embodiments, the lifting column 522 is provided with a first slide groove 5221 , the first slide groove 5221 extends in the up-down direction, and the mounting portion 511 is provided with a first sliding member, and the first sliding member is arranged in the first slide groove 5221 .

[0050] The cooperation between the first sliding member and the first sliding groove 5221 limits the moving direction of the lifting column 522 , and the lifting column 522 can only move in the up and down directions, thereby ensuring the reliability of the pressure plate picking and placing device 500 .

[0051] In some specific embodiments, the first sliding member may be a slider, which has a simple structure and reduces costs. In other specific embodiments, the first sliding member may also be a roller, which abuts against the inner wall of the first slide groove 5221, thereby reducing the friction between the first sliding member and the inner wall of the first slide groove 5221 and improving the smoothness of the movement of the lifting column 522. It should be understood that the first sliding member may also be other structures, which are not limited by the present invention.

[0052] In some embodiments, the first driving assembly 521 includes: a first driving motor, a gear and a rack 5211 , the gear is disposed on the output shaft of the first driving motor, the rack 5211 is disposed on the lifting column 522 , and the gear and the rack 5211 are meshed and matched.

[0053] When the first driving motor rotates forward, the driving gear rotates, and the gear drives the rack 5211 to move downward, thereby driving the lifting column 522 to descend; when the first driving motor rotates reversely, the driving gear rotates, and the gear drives the rack 5211 to move upward, thereby driving the lifting column 522 to rise.

[0054] In the embodiment of the present invention, the first driving assembly 521 has a simple structure and high transmission stability, which not only reduces the cost of the pressure plate picking and placing device 500 but also improves the reliability of the pressure plate picking and placing device 500.

[0055] In other embodiments, the first drive assembly 521 includes a first drive motor, a nut and a screw rod, the nut is rotatably connected to the mounting portion 511, the nut is threadedly connected to the screw rod, the screw rod is slidably connected to the mounting portion 511, and the screw rod is fixedly connected to the lifting column 522. The first drive motor is suitable for driving the nut to rotate, and the nut drives the screw rod to move to achieve the movement of the lifting column 522. It should be understood that the first drive assembly 521 can also be other structures, as long as it can drive the lifting column 522 to move up and down, and the present invention is not limited to this.

[0056] In some further embodiments, the first drive motor is configured as a servo motor. When the platen pick-up and placement device 500 is suddenly powered off, the first drive motor self-locks the brake to limit the movement of the lifting column 522, thereby avoiding the risk of the lifting column 522 suddenly falling and improving the safety of the platen pick-up and placement device 500.

[0057] In some embodiments, the lifting column 522 is provided with a positioning hole, the mounting portion 511 is provided with a fourth driving assembly and a positioning column, and the fourth driving assembly is used to drive the positioning column to insert into the positioning hole to limit the movement of the lifting column 522. The risk of the lifting column 522 falling suddenly is further reduced.

[0058] In some further embodiments, the positioning hole is disposed at one end of the lifting column 522 close to the stop plate 530 .

[0059] Through the above technical solution, when the positioning column is inserted into the positioning hole, the lifting column 522 can be positioned away from the battery tray to prevent the lifting column 522 from affecting the welding of the battery tray.

[0060] In some embodiments, there are multiple positioning holes, which are arranged along the length direction of the lifting column 522. The fourth driving assembly can drive the positioning column to be inserted into any positioning hole to position the lifting column 522 at different heights. This is convenient for the staff to detect the movement of the lifting column 522 when repairing the pressure plate picking and placing device 500.

[0061] In some specific embodiments, the fourth driving component includes a first oil cylinder, and the positioning column is connected to the piston of the first oil cylinder. When the lifting column 522 moves to the position where the positioning hole is opposite to the positioning column, the first oil cylinder can drive the positioning column to insert into the positioning hole to realize the positioning of the lifting column 522. The first oil cylinder can also drive the positioning column to disengage from the positioning hole to release the positioning of the lifting column 522.

[0062] Reference Figure 4 and Figure 5 In some embodiments, the stop plate 530 is movably disposed on the lifting column 522 , and a first elastic member 532 is disposed between the lifting column 522 and the stop plate 530 .

[0063] After the battery tray completes the welding operation, the first drive assembly 521 drives the lifting column 522 to descend, and the stop plate 530 at the bottom of the lifting column 522 descends together with the lifting column 522. When the stop plate 530 contacts the pressure plate 600, the first elastic member 532 can buffer the collision between the stop plate 530 and the pressure plate 600, thereby achieving a soft landing of the stop plate 530 and avoiding damage to the battery tray when the stop plate 530 descends; after the battery tray to be welded is placed on the fixture 2000, the first drive assembly 521 drives the lifting column 522 to descend, and the pressure plate 600 positioned on the stop plate 530 descends together with the lifting column 522. When the pressure plate 600 contacts the battery tray, the first elastic member 532 can buffer the collision between the pressure plate 600 and the battery tray, thereby achieving a soft landing of the pressure plate 600 and avoiding damage to the battery tray when the pressure plate 600 descends, thereby effectively improving the reliability of the pressure plate picking and placing device 500.

[0064] In some embodiments, a third sliding member 533 is provided on the top of the stop plate 530, and the third sliding member 533 is slidably connected to the bottom of the lifting column 522. The third sliding member 533 is provided with a limiting member 534, and the limiting member 534 is suitable for stopping with the lifting column 522 to limit the third sliding member 533 from separating from the lifting column 522.

[0065] The above technical solution limits the moving direction of the stop plate 530 through the sliding connection between the third sliding member 533 and the lifting column 522, ensures the stability of the up and down movement of the stop plate 530, and avoids the risk that the first positioning member 610 cannot pass through the first through hole 531.

[0066] In some specific embodiments, the bottom end of the lifting column 522 is connected to a first plate body 5222, and the stop plate 530 is connected to a plurality of third sliding members 533, and the third sliding members 533 are configured as guide columns, and the plurality of guide columns are spaced apart and are all disposed through the first plate body 5222. The stability of the up and down movement of the stop plate 530 is further ensured by the sliding cooperation between the plurality of guide columns and the first plate body 5222.

[0067] The limiting member 534 is disposed at the top end of the guide post and extends in the radial direction of the guide post. The limiting member 534 is suitable for abutting against the top surface of the first plate body 5222 to limit the guide post from separating from the first plate body 5222 .

[0068] In the above technical solution, the structures of the limiting member 534 and the third sliding member 533 are simple, which reduces the cost of the pressure plate picking and placing device 500.

[0069] Reference Figure 4 and Figure 5In some embodiments, the first locking assembly 540 includes a second driving assembly and a first movable member 542. The second driving assembly is used to drive the first movable member 542 to switch between a first position and a second position. When the first movable member 542 is in the first position, the first movable member 542 is engaged with the first positioning member 610 to limit the first positioning member 610 from being disengaged from the first through hole 531. When the first movable member 542 is in the second position, the first movable member 542 is disengaged from the first positioning member 610.

[0070] In the embodiment of the present invention, the first locking assembly 540 has a simple structure, which reduces the cost of the pressure plate taking and placing device 500.

[0071] In some specific embodiments, the upper end of the first positioning member 610 is provided with a protrusion 611 extending radially of the first positioning member 610 , and when the first movable member 542 is in the first position, at least a portion of the first movable member 542 is located between the protrusion 611 and the stop plate 530 .

[0072] By clamping the first movable member 542 between the protrusion 611 and the stop plate 530 , the movement of the protrusion 611 toward the stop plate 530 is restricted, thereby restricting the first positioning member 610 from being separated from the first through hole 531 , and fixing the pressing plate 600 on the stop plate 530 .

[0073] In some further embodiments, the protrusion 611 is formed as an annular structure, and the first movable member 542 is provided with a U-shaped opening 5421 adapted to the first positioning member 610. When the first movable member 542 is in the first position, a portion of the first positioning member 610 is located in the U-shaped opening 5421, the protrusion 611 is located outside the U-shaped opening 5421, and a portion of the first movable member 542 abuts against the bottom surface of the protrusion 611.

[0074] Through the above technical solution, the contact area between the first movable member 542 and the protruding portion 611 is increased, and the reliability of the first movable member 542 locking the first positioning member 610 is further improved.

[0075] In some embodiments, the first movable member 542 is also provided with an avoidance groove 5422 for avoiding the protrusion 611. When the first movable member 542 moves relative to the first positioning member 610, the protrusion 611 can be set in the avoidance groove 5422 and move relative to the inner wall of the avoidance groove 5422. When the first movable member 542 is in the first position, the bottom wall of the avoidance groove 5422 stops against the bottom wall of the protrusion 611.

[0076] If the first movable member 542 is not provided with the avoidance groove 5422, it is necessary to reduce the overall thickness of the first movable member 542 or increase the height of the first positioning member 610. However, reducing the overall thickness of the first movable member 542 is not conducive to the strength of the first movable member 542, and increasing the height of the first positioning member 610 is likely to cause the first positioning member 610 to interfere with other mechanisms when the battery tray is installed, and is not conducive to the strength of the first positioning member 610.

[0077] In the above technical solution, by setting the avoidance groove 5422 on the first movable part 542, while ensuring the strength of the first movable part 542, the height of the first positioning part 610 can be reduced, reducing the risk of interference between the first positioning part 610 and other mechanisms and helping to ensure the strength of the first positioning part 610.

[0078] In some embodiments, the first movable member 542 is provided with a second sliding member 543 , the stop plate 530 is provided with a second sliding groove, and at least a portion of the second sliding member 543 is located in the second sliding groove.

[0079] In the above technical solution, the sliding cooperation between the second sliding member 543 and the second sliding groove realizes the sliding connection between the first movable member 542 and the stop plate 530, limits the moving direction of the first movable member 542, and improves the stability of the movement of the first movable member 542.

[0080] In some specific embodiments, the portion of the second sliding member 543 located in the second chute can be a slider, which has a simple structure and reduces costs. In other specific embodiments, the portion of the second sliding member 543 located in the second chute can also be a roller, which abuts against the inner wall of the second chute to reduce the friction between the second sliding member 543 and the inner wall of the second chute, thereby improving the smoothness of movement of the first movable member 542. It should be understood that the portion of the second sliding member 543 located in the second chute can also be other structures, and the present invention is not limited thereto.

[0081] In some further embodiments, the stop plate 530 is further provided with a first mounting member 535 and a second mounting member 536, which are distributed at both ends of the second slide groove, and a retractable dust cover 537 is connected between the first mounting member 535 and the second sliding member 543, and a retractable dust cover 537 is also connected between the second mounting member 536 and the second sliding member 543. The dust cover 537 is used to shield the second slide groove to prevent foreign objects from entering the second slide groove and affecting the sliding of the second sliding member 543, thereby ensuring the smooth movement of the first movable member 542.

[0082] Because retractable dust covers 537 are provided on both sides of the second sliding member 543, no matter where the second sliding member 543 is in the second sliding groove, the dust covers 537 on both sides of the second sliding member 543 can completely cover the second sliding groove, further reducing the risk of foreign matter entering the second sliding groove.

[0083] In some specific embodiments, the first movable member 542 is provided with two second sliding members 543, and the two second sliding members 543 are distributed at both ends of the first movable member 542.
