Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Please refer to Figure 1 An embodiment of the present utility model provides a pallet displacement mechanism, including a workbench 30, a slide rail 31, a slider 32, a pallet ejection device 33, a pallet tightening device 34, a displacement drive device 35 and a limit baffle 36. The following is a detailed description of the various components of this embodiment in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, two slide rails 31 can be provided and are respectively and spaced apart and parallelly arranged on the top surface of the workbench 30. The pallet tightening device 34 and the pallet ejecting device 33 are on the same horizontal line in the vertical direction. The bottom sides of the pallet tightening device 34 are slidably connected to the corresponding slide rails 31 through a plurality of sliders 32. The displacement driving device 35 is arranged in parallel on one side of one of the slide rails 31. The output part of the displacement driving device 35 is transmission-connected to one side of the pallet tightening device 34. The limit baffles 36 are respectively fixed at both ends of the two slide rails 31. The pallet ejecting device 33 is installed under the workbench 30 and is located between the two slide rails 31.

[0024] In specific implementation, the displacement driving device 35 can drive the tray tightening device 34 to slide back and forth along the length direction of the slide rail 31, and the tray ejecting device 33 extends out of the lifting plate 331 on the top surface of the workbench 30 and can move up and down under the drive of the tray ejecting device 33.

[0025] Among them, two parallel slide rails 31 provide support and guidance, ensuring that the tray clamping device 34 can slide smoothly along its length direction. The tray ejecting device 33 can eject the tray, enabling the rapid and effective ejection or temporary storage of the tray. The tray clamping device 34 can clamp and fix the ejected tray to ensure that the tray will not fall during displacement. The tray ejecting device 33 and the tray clamping device 34 cooperate together to achieve an efficient and stable work process, which is suitable for occasions where the tray needs to be frequently replaced or displaced.

[0026] Preferably, the displacement driving device 35 can be set as a linear driving module.

[0027] As Figure 2 shown, the tray ejecting device 33 can include a lifting cylinder 332, a lifting cylinder mounting plate 333, a lifting fixing plate 334, a lifting driving plate 335, a lifting side plate 336, a lifting guide rod 337, and a lifting guide sleeve 338. The lifting fixing plate 334 is fixedly arranged on the bottom surface of the workbench 30. There are two lifting side plates 336, which are respectively vertically movably inserted through the workbench 30. There are two lifting plates 331, which are respectively arranged on the tops of the lifting side plates 336. The lifting driving plate 335 is fixedly arranged at the bottom of the lifting side plate 336. One end of the lifting guide rod 337 is fixedly connected to the bottom surface of the lifting fixing plate 334, and the other end of the lifting guide rod 337 passes downward through the lifting guide sleeve 338 inserted on the lifting driving plate 335 and is fixedly connected to the lifting cylinder mounting plate 333. The lifting cylinder 332 is fixedly installed at the bottom of the lifting cylinder mounting plate 333. The output shaft of the lifting cylinder 332 is in transmission connection with the bottom surface of the lifting driving plate 335. The lifting cylinder 332 can drive the lifting driving plate 335 to move up and down, thereby driving the lifting plate 331 to move up and down.

[0028] Among them, the lifting side plate 336 serves as the support for the lifting plate 331, which can provide good guidance, making the movement of the lifting plate 331 more stable. The lifting guide sleeve 338 cooperates with the lifting guide rod 337 to provide guidance and reduce friction, ensuring the smooth movement of the lifting driving plate 335, improving the overall operation efficiency, and extending the service life.

[0029] As Figure 3As shown, the tray pressing device 34 may include a support bottom plate 341, support side plates 342, side stoppers 343, tray movable members 344, a pressing module 345, and a stopping module 346. The support bottom plate 341 has an inverted "U" - shaped structure. The two sides of the support bottom plate 341 are respectively fixedly connected to the top surfaces of the sliders 32. Two support side plates 342 are provided and are respectively vertically and fixedly arranged on the two top sides of the support bottom plate 341. Two side stoppers 343 are provided and are relatively fixedly arranged at the top ends of one side wall of the two support side plates 342. Four tray movable members 344 are provided and are respectively arranged in pairs opposite to each other on the outer walls of the two support side plates 342. The supporting blocks 3441 of the tray movable members 344 can all extend into the inner walls of the support side plates 342. The pressing module 345 is installed inwardly on one of the support side plates 342. Two stopping modules 346 are provided and are installed inwardly at the top ends of the other side walls of the two support side plates 342 and respectively correspond to the two side stoppers 343.

[0030] Among them, the support bottom plate 341 with an inverted "U" - shaped structure can keep the tray pressing device 34 stable during displacement, prevent tilting, and has good load - bearing capacity. The tray movable members 344 can flexibly support the tray.

[0031] As Figure 4 and Figure 5 As shown, the tray movable member 344 may include a supporting block 3441, a rotating shaft 3442, and a fixed seat 3443. An activity groove 3444 is opened in the middle of the inner wall of the fixed seat 3443. The bottom ends of the supporting blocks 3441 are respectively rotatably installed between the activity grooves 3444 through the rotating shafts 3442. A receiving space 3445 is left between the back of the supporting block 3441 and the inner end surface of the activity groove 3444. The upper part of the front of the supporting block 3441 is arranged in an inverted right - angled triangle structure and can extend out of the inner wall of the support side plate 342. The lower part of the front of the supporting block 3441 is in contact with the outer wall of the support side plate 342.

[0032] During specific implementation, when each supporting block 3441 is located at the bottom of the tray, the top surface of the supporting block 3441 can support the bottom of the tray. When the tray moves upward along the bottom inclined surface that extends out of the supporting block 3441 from the support side plate 342, the supporting block 3441 can retract into the receiving space of the activity groove 3444 and will not block the upward - moving tray in the vertical direction. The structure is simple and has good flexibility.

[0033] As Figure 6As shown, the tightening module 345 may include a tightening block 3451, a tightening driving cylinder 3452, and a tightening cylinder mounting seat 3453. The tightening cylinder mounting seat 3453 is horizontally and fixedly arranged at the upper end of the outer wall of one of the supporting side plates 342. The tightening driving cylinder 3452 is fixedly arranged on the top surface of the tightening cylinder mounting seat 3453. The tightening block 3451 is in transmission connection with the output part of the tightening driving cylinder 3452 and is movably arranged in a rectangular groove 3421 at the upper end of the outer wall of the supporting side plate 342.

[0034] As Figure 7 shown, the stopping module 346 may include a stopping screw 3461, a stopping driving cylinder 3462, and a stopping connecting block 3463. The stopping driving cylinders 3462 are respectively arranged outward at one ends of the two supporting side plates 342 away from the side stoppers 343. The structure of the stopping connecting block 3463 is arranged in an inverted L shape. The vertical section of the stopping connecting block 3463 is in transmission connection with the output shaft of the stopping driving cylinder 3462. The stopping screw 3461 is horizontally inserted at the end of the horizontal section of the stopping connecting block 3463 with its screw end facing the side stopper 343.

[0035] Among them, the stopping module 346 can cooperate with the side stoppers 343 to limit the material tray at both ends thereof, ensuring that the tray can remain stable at a predetermined position during the tightening and displacement processes, and can also achieve the rapid release and positioning of the stopping screws 3461, with good flexibility.

[0036] The working principle of the present utility model is as follows:

[0037] When the material tray is transferred by an external conveying device to above the lifting plates on both sides of the top of the tray ejecting device, the lifting cylinders drive the two lifting plates to move upward so that their top surfaces are in contact with the bottom surface of the material tray. Then, the displacement driving device drives the tray tightening device to move on the slide rail in the direction close to the tray ejecting device. When the two supporting side plates are located on both sides of the material tray and the side stoppers are in contact with one end of the material tray, the tray ejecting device moves downward, and the bottom of the material tray can be in contact with the top of the supporting blocks of each tray moving part. The tightening block on one of the supporting side plates is driven by the tightening driving cylinder to press against one side of the material tray and make the other side of the material tray abut against the inner wall surface of the supporting side plate. At the same time, the stopping driving cylinder can drive the stopping screws to move towards both ends of the material tray and press both ends of the material tray until the material tray is fixed on the tray tightening device. Finally, the displacement driving device drives the material tray on the tray tightening device to move back and forth along the length direction of the slide rail.

[0038] In summary, the present utility model can realize the functions of smoothly ejecting the material tray, accurately positioning, stably supporting, and smoothly displacing the material tray, with a high degree of automation, greatly improving the work efficiency, reducing manual intervention, and ensuring the safety and accuracy of the operation.

[0039] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
