[0037] Specifically, the guide rail 353 is arranged in a horizontal direction.

[0038] like Figure 1 and Figure 5 As shown, in one embodiment, the unloading assembly 4 further includes an unloading rack 42 and a transverse movement structure 22, the unloading rack 42 is provided with a second conveyor belt, and the transverse movement structure 22 is used to transfer the pallet 1 from the limiting channel 31 to the second conveyor belt.

[0039] like Figure 7As shown, in one embodiment, the coating structure 41 includes a shift bracket 411, a first suction member 412, a guide plate 413, a clamp 414, a coating frame 415 and a film rolling roller 416. The movable bracket and the coating frame 415 are respectively installed on the workbench 8 at intervals. The first suction member 412 and the clamp 414 are respectively slidably assembled on the shift bracket 411. The guide plate 413 is fixed on the coating frame 415. The first suction member 412 is located above the guide plate 413 and is used to transfer the pallet 1 from the second conveyor belt to the coating plate. The film rolling roller 416 is rotatably installed on the coating frame 415. The protective film is wound on the film rolling roller 416. The clamp 414 is used to unwind the protective film from the film rolling roller 416 and coat the pallet 1 on the guide plate 413. In this way, by providing a first suction member 412, the sliding of the first suction member 412 on the shift bracket 411 enables it to keep synchronous movement with the clamping jaw 414, so that when the protective film is coated on the pallet 1, the protective film can be pressed and fitted on the pallet 1 to complete the coating of the surface of the mold 7 inside the pallet 1; by providing a clamping jaw 414, the movement of the clamping jaw 414 can unwind the protective film wound on the film winding roller 416, which is conducive to coating the unwound protective film on the pallet 1; by providing a guide plate 413, when the protective film is unrolled, the guide plate 413 can provide a certain support position for the protective film, so that it remains in a straight state, which is convenient for subsequent coating operations.

[0040] Specifically, the first suction member 412 is provided with a suction head which can move up and down relative to the film-covering plate.

[0041] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, a plurality of interlocking seats 51 interlocking with the mold 7 are arranged at intervals on the conveying frame 5; the adsorption assembly 6 includes a base 61, a connecting arm 62, a connecting head 63 and an adsorption member 64, the base 61 is arranged on one side of the placement position, one end of the connecting arm 62 is rotatably connected to the top of the base 61, the other end of the connecting arm 62 is rotatably connected to the connecting head 63, the adsorption member 64 is plugged into the connecting head 63, and a suction cup 641 is installed at the bottom of the adsorption member 64. In this way, by providing the interlocking seat 51, the stability of the mold 7 during the conveying and loading process is guaranteed to prevent it from falling off; by providing the connecting arm 62 and the connecting head 63, the rotation of the two can drive the adsorption member 64 to adjust its adsorption position, thereby improving the adsorption accuracy of the mold 7.

[0042] like Figure 3 and Figure 4As shown, in one embodiment, the suction cup 641 includes a suction head 6411 and a connecting seat 6412 installed at the bottom of the adsorbent 64, a groove is provided in the connecting seat 6412, the suction head 6411 is arranged on the end of the groove through the connecting member and protrudes out of the groove, and a pulling structure for twisting the suction head 6411 is also provided between the suction head 6411 and the connecting seat 6412.

[0044] like Figure 4 As shown, further, the pulling structure includes a pull rod 6415 and a screw 6416; the pull rod 6415 is an inverted "L" shape, and its lower end is connected to the eccentric position of the suction head 6411, and its upper flat plate part is connected to the connecting seat 6412 through the cooperation between the screw 6416 and the screw 6416 hole on the bottom surface of the groove.

[0045] When the suction cup 641 is in use, the connecting seat 6412 moves downward under the gravity of the mold 7, and transmits force to the suction head 6411 through the connecting piece. The suction head 6411 is deformed by the force, and the middle part moves downward. The gas in the spherical cap is discharged from the periphery, and a closed negative pressure cavity is formed between the suction head 6411 and the mold 7. The pressure difference between the inside and outside of the suction head 6411 is used to firmly adsorb the entire suction cup 641 on the mold 7.

[0046] In addition, when the adsorption position of the mold 7 needs to be adjusted, the connecting seat 6412 is twisted circumferentially, and the pull rod 6415 twists the suction head 6411 to deform the suction head 6411, breaking the seal between the suction cup 641 and the mold 7, allowing air to enter the suction head 6411, releasing the adsorption of the suction head 6411 on the mold 7, and the entire suction cup 641 can move freely under the action of external force.

In this way, by providing a second suction piece 92, the sliding of the second suction piece 92 on the second loading rack 91 enables it to transfer the cover plate 10 to the top of the pallet 1 and complete the covering and sealing of the pallet 1; by providing a lifting cylinder 94, the lifting cylinder 94 drives the lifting movement of the upper cover top plate 95, so that the cover plate 10 on the upper cover top plate 95 can be reciprocated to lift the height, which is convenient for the second suction piece 92 to adsorb and clamp the cover plate 10.

[0048] Specifically, the second suction member 92 is also provided with a suction head which can move up and down relative to the film-covering plate.

[0049] Working principle:

[0050] First, the pallet 1 is loaded and transported from the first conveyor belt. When the pallet 1 is transported to the discharge end of the first conveyor belt, the transverse movement structure 22 in the loading assembly can transfer the pallet 1 to the limiting channel 31 for placement and installation. Then, the pallet 1 is driven by the moving structure 35 to complete the position movement on the limiting channel 31. When it moves to the placement position, the limiting cylinder 32 controls the clamping fixture 33 to clamp and fix the position of the pallet 1.

[0051] At the same time, the mold 7 is loaded and transported from the conveying rack 5. During the conveying process of the mold 7, the adsorption component 6 transfers the mold 7 from the conveying rack 5 to the tray 1 fixed at the placement position, thereby completing the storage of the mold 7.

[0052] After the mold 7 is stored, the tray 1 continues to move on the limiting channel 31 driven by the moving structure 35, and finally moves to the unloading position, and then the laminating structure 41 is started, and the protective film is unrolled from the film roller 416 and extends to the top of the tray 1 under the traction of the clamping claw 414, and is pressed against the upper surface of the tray 1 under the drive of the first suction member 412. After the pressing is completed, the protective film is cut manually by the operator or with the help of other automated equipment to complete the laminating operation;

[0053] After the surface coating of the tray 1 is completed, the second suction member 92 sucks and transfers the cover plate 10 to the tray 1 for covering, completing the sealed package, and then the transverse movement structure 22 in the unloading component 4 is used to transfer the tray 1 to the second conveyor belt for unloading.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
