[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0017] First, combine Figures 1-4 This invention describes a 180° rotating mechanism for a pallet according to an embodiment of the present invention, which is used to achieve the rotation of the pallet and has a wide range of applications.

[0018] like Figures 1-4As shown, an embodiment of the present invention provides a 180° rotating mechanism for a pallet, comprising a base plate 100, a rotating module, a fixing plate 300, four support blocks 400, and two positioning pins 500.

[0019] Specifically, such as Figures 1-4 As shown, the rotation module is located on the top of the base plate 100, providing the driving force for rotational movement. The rotation module includes: a rotating shaft 201, a gear 202, a rodless cylinder 203, and a rack 204. The bottom of the rotating shaft 201 is rotatably connected to the base plate 100, and the top of the rotating shaft 201 is fixed to the bottom of the fixed plate 300; the gear 202 is sleeved on the rotating shaft 201; the rodless cylinder 203 is located on the base plate 100; the rack 204 is slidably connected to the base plate 100, and the rack 204 is connected to the output end of the rodless cylinder 203, meshing with the gear 202. By controlling the operation of the rodless cylinder 203, the rack 204 can be moved, thereby driving the gear 202 to rotate, thus causing the rotating shaft 201 to rotate.

[0020] Furthermore, such as Figures 1-4 As shown, the rotating module also includes a guide rail 205 and a slider 206. The guide rail 205 is mounted on the base plate 100; the slider 206 is slidably connected to the guide rail 205 and is connected to the rack 204. The guide rail 205 and the slider 206 ensure the stability of the rack 204 during movement.

[0021] Specifically, such as Figures 1-4 As shown, the fixed plate 300 is set at the output end of the rotating module (i.e., the rotating shaft 201), and rotates with the rotating shaft 201 under the action of the rotating module.

[0022] Specifically, such as Figures 1-4 As shown, four support blocks 400 are located at the top four corners of the fixed plate 300 to support the external tray.

[0023] Specifically, such as Figures 1-4 As shown, two positioning pins 500 are respectively set on the top of two diagonally positioned support blocks 400. One positioning pin 500 is rhomboid and the other is cylindrical, and they are used to cooperate with the positioning holes on the tray for positioning.

[0024] Furthermore, such as Figures 1-4As shown, a 180° rotation mechanism for a pallet according to an embodiment of this utility model further includes: two supports 601, two buffers 602, two limiting sleeves 603, and two limiting blocks 604. The two supports 601 are disposed on the top sides of the base plate 100; the two buffers 602 are respectively disposed on the two supports 601; the two limiting sleeves 603 are respectively disposed at the head ends of the two buffers 602; and the two limiting blocks 604 are disposed at the bottom of the fixed plate 300. The two limiting blocks 604, as the fixed plate 300 rotates, cooperate with the two buffers 602 and the two limiting sleeves 603 to limit and buffer the 180° rotation. When the rotation is about to reach 180°, the limiting block 604 first contacts the buffer 602 for buffering, and finally contacts the limiting sleeve 603 to be restricted, achieving a precise 180° rotation.

[0025] Furthermore, such as Figures 1-4 As shown, a 180° rotating mechanism for a tray according to an embodiment of the present invention further includes: two slotted photoelectric sensors 605 and a measured component 606. The two slotted photoelectric sensors 605 are disposed on the top sides of the base plate 100; the measured component 606 is disposed on the bottom of the fixed plate 300. The measured component 606 rotates with the fixed plate 300, and when the measured component 606 is detected by the slotted photoelectric sensor 605, it indicates that the rotation position has been reached.

[0026] Working principle: The 180° rotation mechanism is installed on the lifting mechanism of the conveyor line. When the pallet flows over this mechanism, the lifting mechanism lifts the 180° rotation mechanism and removes the pallet from the conveyor line. At the same time, the two positioning pins 500 of the 180° rotation mechanism are inserted into the positioning holes of the pusher plate. Then the rotation module moves, driving the fixing plate 300 and the pallet to rotate 180°. Then the slotted photoelectric sensor 605 detects whether the 180° rotation position has been reached.

[0027] Above, refer to Figures 1-4 A 180° rotating mechanism for a tray according to an embodiment of the present invention is described, which has the following beneficial effects: 1. It can be fixed and integrated into the production line to meet the requirement of automatic 180-degree rotation of the pallet, greatly improving the efficiency of pallet rotation work; 2. Simple structure, low cost, and low operating expenses; 3. When the limit block 604 is rotated into position, the hydraulic buffer 602 ensures smooth buffering.
