[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] See also Figure 1-Figure 3 , this application provides the following technical solutions:

[0046] A pallet supply mechanism includes a pallet rack 31 of a rectangular frame structure, on which a pallet slide 311 corresponding to the pallet is provided, and the pallet can slide on the pallet rack 31 through the pallet slide 311; one end of the pallet 311 extends to the feeding side of the pallet rack 31, and the other end extends to the discharging side of the pallet rack 31. A first supply mechanism 32 and a second supply mechanism 33 are also provided on the pallet rack 31, and the supply paths of the two are both straight paths. The first supply mechanism 32 takes the feeding side of the pallet rack 31 as a starting point, and can supply the pallet to the middle position of the pallet rack 31; the second supply mechanism 33 takes the discharging side of the pallet rack 31 as an end point, and its supply starting point is close to the starting point of the first supply mechanism 32.

[0047] This solution combines two supply mechanisms to form an overall supply path for the tray rack 31. The combination of the two supply mechanisms can, on the one hand, reduce the high manufacturing cost of a single supply structure due to the long path length, and on the other hand, can also reduce the difficulty of maintenance in the later use of the equipment and reduce repair and maintenance costs.

[0048] Based on the above implementation scheme, see Figure 1 and Figure 2 The first supply mechanism 32 includes a first supply push frame 321 and a first supply drive mechanism 322. The frame body of the first supply push frame 321 can be moved to the lower side of the pallet. The first supply push frame 321 includes a first frame plate, which is a "Y"-shaped plate body with a plurality of mounting holes. The frame plate is connected to the first supply drive mechanism 322, and push blocks are respectively provided at the two branch ends of the frame plate on the same side. The push block is provided at a position on the first frame plate facing the feeding side of the pallet frame 31. When the first supply push frame 321 moves, the push block abuts against the edge of the pallet near it. The first supply drive mechanism 322 uses a rodless cylinder to drive the first supply push frame 321 to translate toward the middle area of ​​the pallet frame 311.

[0049] Based on the above implementation scheme, see Figures 3 to 5 The second supply mechanism 33 includes a second supply push frame 331 and a second supply drive mechanism 332. The upper part of the second supply push frame 331 can extend to the side of the tray toward the feeding side of the tray frame 31; the second supply drive mechanism 332 is linked with the second supply push frame 331 to drive the second supply push frame 331 to translate toward the discharging side of the tray frame 311.

[0050] The second supply push rack 331 is composed of a second frame plate 3311, a second vertical frame 3312 and a second push rod 3313. The second frame plate 3311 is an isosceles trapezoidal plate body, and its plate body is linked to the second supply drive mechanism 332. Two second vertical frames 3312 are symmetrically arranged on both sides of the long side of the second frame plate 3311, and the second vertical frames 3312 are extended upward. A second push rod 3313 is rotatably arranged at the upper end of each second vertical frame 3312, and the rod body of the second push rod 3313 is rotatably connected to the upper part of the second vertical frame 3312; in a natural state, the second push rod 3313 maintains an inclined state, and its end facing the feeding side of the tray frame 31 is located at a low horizontal position, that is, Figure 3 , Figure 4 and Figure 5 In the state shown in , the lower edge of the second push rod 3313 is in contact with the upper structure of the second stand 3312. When the second supply push rack 331 moves toward the discharge side, the second push rod 3313 will not rotate further due to the limit of the second stand 3312, so the tray can be pushed to move. When the first supply push rack 321 pushes the tray to move to the second supply push rack 331, the tray first pushes the second push rod 3313 to rotate. As the second push rod 3313 is pushed to become close to the horizontal state, the tray can continue to move forward by passing the upper side of the second push rod 3313. After the tray leaves the second push rod 3313, the second push rod 3313 resumes its tilted state under the action of the deadweight of the rod body.

[0051] Different from the first supply drive mechanism 322, the second supply drive mechanism 332 adopts a screw structure as a drive structure, including a second drive seat 3321 fixedly arranged inside the tray frame 31, the second drive seat 3321 is located below the first supply mechanism 32, and the second drive seat 3321 is a long track structure, such as Figure 6 As shown, the interior of the second drive seat 3321 is a cavity, and the second screw rod is rotatably connected in the cavity and rotatably arranged in the interior of the second drive seat 3321. The second motor 3322 is fixedly connected to one end of the second drive seat 3321, and its motor shaft is linked to the second screw rod. The second sliding seat 3323 is also slidably connected in the cavity, and the two sides of the second drive seat 3321 extend outside the cavity. The lower part of the second sliding seat 3323 is located in the second drive seat 3321 and is threadedly connected to the second screw rod. The upper part is fixedly connected to the second frame plate 3311 in the second supply push rack 331. Because the second supply push rack 331 needs to ensure docking with the external tray loading mechanism, a screw-driven structure is adopted. Compared with the cylinder execution action, the screw structure is more accurate in adjusting the position and is easy to debug.

[0052] On the basis of the above implementation scheme, this mechanism needs to be used in conjunction with an external loading mechanism in industrial processing, so the displacement of the second supply mechanism 332 needs to be controlled. This solution provides a design method for a control mechanism. The second supply drive mechanism 332 also includes: a second sensor group 3324, including a plurality of second sensors arranged on the outside of the second drive seat 3321, and the second sensor is a photoelectric sensor. A second trigger member is fixedly connected to the second sliding seat 3323, and the second trigger member is a bent plate structure. When the second sliding seat 3323 moves to the second sensor position, the second trigger member excites the second sensor to make an electrical signal feedback.

[0053] On the basis of the above implementation scheme, a roller group and a pad group are provided at the lower part of the frame of the pallet rack 31; the pad is a bolt structure with adjustable height. The roller group and the pad group are arranged in combination to facilitate the turnover of the mechanism and positioning during use. The pallet rack 31 also includes a pallet guide plate 312, and the pallet guide plate 312 is arranged on the upper side of the pallet slide 311. The end of the pallet guide plate 312 facing the feed side of the pallet rack 31 is a trumpet structure. The position of the pallet is adjusted by the pallet guide plates 312 on both sides to facilitate combination with an external tray loading mechanism. The pallet guide plate 312 is fixedly connected to the outer wall of the pallet rack 31 through the pallet guide mounting member 313. A plug rod is provided on the upper part of the pallet guide mounting member 313 toward the middle part of the pallet rack 31, and the pallet guide plate 312 is plugged into the plug rod of the pallet guide mounting member 313. As shown Figure 4As shown, the insertion rod is arranged horizontally, and a locking rod is threadedly connected to the upper side of the insertion rod, and the insertion rod is fixed by the locking rod. The tray guide plate 312 is provided with a sliding groove corresponding to the insertion rod, which can facilitate the position adjustment of the tray guide plate 312.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
