The L-shaped bracket 601 and the robotic arm 603 are connected by a damping bearing seat 602, and the angle between the axis of the limiting baffle 313 and the vertical direction is 30°.

[0023] The aforementioned insert plate 306 is equidistantly spaced on the top of a base plate 308.

[0024] The top tray 301 and the bottom tray 305 are each provided with a number of partitions 315 at intervals, and a number of slots 314 are provided along the length of the partitions 315.

[0025] The aforementioned robotic arm 603 is fixedly connected to a connecting plate 613 with a limiting rod 612. The limiting rod 612, which is parallel to the robotic arm 603, is slidably connected to a limiting plate 609 installed on the side wall of the support plate 606.

[0026] The working principle is as follows: During production, the pallet mechanism supports the top pallet connected above the bottom pallet through the connecting rods on both sides. When loading, the fingerprint module can be sorted and arranged by the feeder and pushed synchronously through the feeding slot to the multiple partitions in the top and bottom pallets, quickly completing the loading of double-layer materials. At this time, the empty slot is located between the partitions of the bottom pallet. When the pallet mechanism moves and stabilizes at the workstation along with the circulating conveyor, the connecting rod moves under the action of the robotic arm, causing the top pallet to move to one side of the bottom pallet, exposing the top of the bottom pallet. Under the push of the pneumatic rod, the bottom of the insert plate is inserted between multiple partitions to limit the parts. The spacing between the multiple insert plates can meet the clamping space required by the fixture. Then the insert plate moves down, and under the action of the torsion spring, it drives the top pallet to return to its position. The insert plate then moves up again and inserts into the top pallet to limit the parts, and then clamps the parts in the top pallet. In this way, the purpose of assembling multiple parts in a single operation can be achieved, increasing the single conveying capacity of the pallet and greatly reducing the operating frequency of the conveyor mechanism, thereby saving costs. At the same time, the automatic limiting function attached to the pallet can also reduce the difficulty of material sorting and further improve the feeding efficiency. During transport, a complete loop is formed by the first and second conveying slide rails, as well as the first and second switching slide rails located at both ends. After the pallet mechanism is loaded onto the first conveying slide rail, it moves to the first switching slide rail and establishes a connection with the second conveying slide rail by moving along the second screw slide rail. This completes the movement of the pallet mechanism to the second conveying slide rail. The second conveying slide rail then connects with multiple reciprocating slide rails through the second switching slide rail. At this time, the length of the first screw slide rail can be extended to set up more reciprocating slide rails, thereby creating more workstations. The transfer of the pallet mechanism and the transport of the empty pallet mechanism to the first conveying slide rail can all be carried out through the second switching slide rail. By adjusting the moving speed of the first screw slide rail and the loading speed of the feeder, sequential feeding of multiple workstations can be achieved, further improving the working efficiency during fingerprint module production. Once the pallet mechanism moves to the workstation, the robotic arm joints straighten, and the pneumatic rod drives the L-shaped connecting rod to move, causing the slider to move synchronously in the first and second slide grooves. This causes the L-shaped bracket to engage with the inclined groove. Through the continuous operation of the pneumatic rod, the L-shaped bracket pulls the connecting rod, moving the top pallet. This structure can save space required for the translation structure while ensuring translation stability, thereby reducing the distance between adjacent reciprocating slide rails and lowering the overall equipment's footprint requirements.

[0027] When the above-mentioned automatic pallet feeding device is used, it feeds materials along the circulating conveyor mechanism through the support shell with top pallet and bottom pallet, realizing the reciprocating circulation of pallets on the base, reducing equipment costs. It can also receive materials through the top pallet and bottom pallet respectively, increasing the single carrying capacity of materials while reducing the floor space, and greatly improving the feeding efficiency. Furthermore, it drives the L-shaped support to rotate through the retraction of the air rod. With the cooperation of the inclined groove and the L-shaped support, the pull rod moves around the axis, so that the top tray can be moved from directly above the bottom tray to one side, which makes it easier to pick up the materials in the bottom tray, reduces the equipment's requirements for operating space, and saves space resources. Furthermore, by having the top and bottom pallets cooperate with the feeding chute, the material transport capacity can be increased during a single feeding process. The bottom plate is moved upward by the pneumatic rod, so that the upper and lower stops of the insert plate can be embedded into the top and bottom pallets, thereby dividing the internal space of the top and bottom pallets into several material units, which is convenient for subsequent gripping by the robotic arm. This not only improves the material transport efficiency but also improves the positional accuracy of the material, reduces the risk of misoperation, and thus improves the overall production efficiency.
