The motor shaft of the clamping drive motor 128 is connected to a clamping plate drive screw 129, and two clamping plate sliding seats 130 with opposite thread directions are threadedly connected to the clamping plate drive screw 129. The two manipulator clamping plates 124 are respectively installed on the two clamping plate sliding seats 130. The clamping mechanism mounting seat 127 is also provided with a clamping plate moving slide rail 131 whose length direction is the same as the axial direction of the clamping plate drive screw 129, and the clamping plate sliding seat 130 is provided with a clamping plate moving slider 132 that slides in cooperation with the clamping plate moving slide rail 131. A driving cylinder 133 is mounted on the clamping plate sliding seat 130. A cylinder connecting plate 134 is mounted on the piston end of the driving cylinder 133. The cylinder connecting plate 134 is connected to the manipulator pressure plate 125 via a guide rod 135, the upper end of which passes through the cylinder connecting plate 134. A compression spring 136 is sleeved on the guide rod 135, with its ends resting against the lower end surface of the cylinder connecting plate 134 and the upper end surface of the manipulator pressure plate 125, respectively. By clamping the stacked trays 8 on both sides and the upper and lower end surfaces, the stability of the clamping is effectively ensured, ensuring that the stacked trays 8 can be accurately positioned for transport and bundling, as well as for the foam wrapping device 105.

[0061] In this embodiment, the foam wrapping equipment 105 includes a foam wrapping frame 108, which is provided with a foam placement groove 109 for stacking multiple pieces of foam. The bottom of the foam placement groove 109 is provided with a foam lifting mechanism 110 that can push the foam out of the foam placement groove 109 from bottom to top. The foam lifting mechanism 110 includes a foam lifting motor 111, and the end of the foam lifting motor 111 is provided with a foam lifting plate 112; the foam wrapping frame 108 is also provided with a foam wrapping table 113 arranged on one side of the foam placement groove 109 and a foam pushing rod mechanism 114 for pushing a single piece of foam extending out of the foam placement groove 109 to the foam wrapping table 113.

When the amount of foam is insufficient, the foam can be directly placed into the foam placement groove 109 from top to bottom by opening the cover at the upper end of the foam observation shell 142.

[0064] During the working process, the foam is first pushed out of the foam placement groove 109 by the foam lifting motor 111, so that the lower surface of the top layer of foam is flush with the foam wrapping table 113. At this time, the top layer of foam can be pushed to the foam wrapping table 113 by the foam pushing cylinder 115, and then the tray 8 stacked after the first bundling is placed on the foam by the robot. Then, the foam wrapping mechanism 137 is started, and the two ends of the foam are first folded into a vertical state along the end of the stacked tray 8 by the vertical folding cylinder 138, and then the vertical foam ends are folded into a horizontal state along the upper end of the stacked tray 8 by the horizontal folding cylinder 140, so that they are folded to the upper end surface of the stacked tray 8, completing the wrapping of the stacked tray 8, and finally the stacked tray 8 wrapped with foam is transported to another strapping machine by the robot for re-bundling to ensure the stability of the foam wrapping and form a stacked tray 8 wrapped with foam.

A plurality of packaging bag suction cups 224 capable of sucking up packaging bags are mounted on the lower end surface of the first suction cup mounting plate 223. The first bag feeding suction cup mounting plate 223 is moved in the length, width, and height directions by a three-dimensional guide rail bracket. This three-dimensional guide rail bracket is a conventional three-dimensional bracket and will not be described in detail here.

[0071] In addition, the conveying mechanism includes a conveying manipulator 225 arranged on the bagging workbench 202, and a desiccant suction disc assembly 226 and a humidity card suction disc assembly 227 are arranged on the conveying manipulator 225. In the embodiment, the bagging workbench 202 is further provided with a first labeling machine 228, a first labeling manipulator 229, and a labeling table 230 for placing the tray 8 to be labeled, and the first labeling manipulator 229 is further provided with a first label suction disc 231 for pasting the label generated by the first labeling machine 228 on the tray 8 to be labeled, and the first labeling manipulator 229 is further provided with a tray clamping mechanism 232 for conveying the tray 8 with the label pasted to the disc placing platform 205.

[0072] The tray clamping mechanism 232 in the embodiment includes a vacuum suction disc for sucking the desiccant and the humidity card, and a suction disc cylinder for controlling the up-down movement of the vacuum suction disc. The desiccant and the humidity card are sucked by the action of the suction disc cylinder and the vacuum suction disc, and then conveyed to the tray 8 with the label pasted by the conveying manipulator 225. The conveying process of the desiccant and the humidity card is carried out by the same manipulator, and only the sucking and placing stages need to be carried out in sequence. The synchronous conveying further saves the conveying time of the desiccant and the humidity card, and the same manipulator is used, which saves the cost while improving the efficiency.

[0073] The desiccant storage mechanism 207 in the embodiment includes a storage tank 234 and a desiccant cutting mechanism 235 arranged at the outlet of the storage tank 234. The storage tank 234 is provided with a material winding shaft 236, and a material winding shaft motor for driving the material winding shaft 236 to rotate is arranged on the storage tank 234. A continuous strip-shaped desiccant is wound on the material winding shaft 236. The desiccant cutting mechanism 235 includes a cutting bottom plate 237, a cutting knife 238 capable of moving up and down is arranged on the cutting bottom plate 237, and a desiccant pressing roller 239 and a desiccant pressing plate 241 for pressing the desiccant to be cut are arranged on the inner side of the cutting knife 238. A desiccant supporting plate 240 for placing the cut desiccant is arranged on the outer side of the cutting knife 238 and can move horizontally to the position of the cutting knife 238.

[0074] The staff winds a continuous strip-shaped desiccant on the material winding shaft 236 in advance. The strip-shaped desiccant is continuously connected by a plurality of independently packaged desiccants, which is produced by a desiccant production device. The strip-shaped desiccant is pressed on the cutting bottom plate 237 by the desiccant pressing roller 239 and the desiccant pressing plate in front of the desiccant pressing roller 239, and then moves to the position of the cutting knife 238 one by one. The cutting knife 238 cuts the desiccant to form a single independently packaged desiccant, and the cut independently packaged desiccant is placed on the desiccant supporting plate 240. Under the action of the cylinder, the desiccant supporting plate 240 moves close to the tray clamping mechanism 232 to facilitate the clamping of the desiccant by the tray clamping mechanism 232.

[0075] In the specific bagging process, the packaging bag and the tray 8 are simultaneously fed to the bagging workbench 202, then a label is generated by the first labeling machine 228, and the first labeling manipulator 229 labels the packaging bag and the tray 8. In this process, the desiccant storage mechanism 207 cuts the continuous strip-shaped desiccant into individual desiccant packs and places the individual desiccant packs on the desiccant pallet 240. Then, the desiccant and the humidity card are transported to the upper end face of the labeled tray 8 by the conveying manipulator 225, and then the tray 8 and the desiccant and humidity card thereon are transported into the packaging bag whose bag opening is opened by the bag opening mechanism 203, and finally, the tray 8 and the desiccant and humidity card thereon are transported to the sealing machine for sealing.

[0076] In the entire bagging process, the packaging bag and the tray 8 can be simultaneously fed, the tray 8, the desiccant, and the humidity card can be simultaneously bagged, and the packaging bag and the tray 8 are labeled before bagging. The entire process has high automation, the entire mechanism is modularly designed, saves space, is convenient to maintain, and has reasonable distribution between the modules, so that the work efficiency can be greatly improved.
