A clamping plate drive screw 129 is connected to the motor shaft of the clamping drive motor 128, 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 installed on the clamping plate sliding seat 130, and a cylinder connecting plate 134 is provided at the piston end of the driving cylinder 133. The cylinder connecting plate 134 is connected to the manipulator clamping plate 125 through a guide rod 135 whose upper end passes through the cylinder connecting plate 134. A clamping spring 136 is sleeved on the guide rod 135, and its two ends respectively abut against the lower end surface of the cylinder connecting plate 134 and the upper end surface of the manipulator clamping plate 125. By clamping the two side surfaces and the upper and lower end surfaces of the stacked tray plates 8, the stability of the clamping can be effectively guaranteed, so as to ensure that the stacked tray plates 8 can be transported and bundled and the foam wrapping device 105 can be accurately positioned.

It is made of a transparent plate, which can well observe whether the foam in the foam placement groove 109 is sufficient. 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 plate on the upper end of the foam observation shell 142.

[0061] 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 uppermost layer of foam is flush with the foam wrapping table 113.

The first bag delivery suction cup mounting plate 223 realizes movement in the length, width and height directions through a three-dimensional guide rail bracket, and this three-dimensional guide rail bracket is a conventional three-dimensional bracket, which will not be described in detail here.

[0068] In addition, the conveying mechanism includes a conveying robot 225 disposed on the bagging workbench 202, and a desiccant suction cup assembly 226 and a humidity card suction cup assembly 227 are installed on the conveying robot 225.

The first labeling robot 229 is also provided with a tray clamping mechanism 232 for transporting the labeled tray 8 to the tray placement platform 205.

[0069] The tray clamping mechanism 232 in this embodiment includes a vacuum suction cup for sucking up the desiccant and the humidity card, and a suction cup cylinder for controlling the up and down movement of the vacuum suction cup. The desiccant and the humidity card are sucked by the suction cup cylinder and the vacuum suction cup, and then the conveying robot 225 simultaneously transports them to the labeled tray 8. The desiccant and the humidity card are transported by the same robot at the same time, and only the suction and placement stages need to be performed in sequence. The synchronous transportation further saves the transportation time of the desiccant and the humidity card, and is achieved by the same robot, which improves efficiency and saves costs.

The desiccant cutting mechanism 235 includes a cutting base plate 237, and the cutting base plate 237 is provided with a cutter 238 that can move up and down, and a desiccant pressing roller 239 and a desiccant pressing plate 241 arranged on the inner side of the cutter 238 for pressing the desiccant to be cut. The outer side of the cutter 238 is also provided with a desiccant support plate 240 that can move horizontally to the position of the cutter 238 and is used to place the cut desiccant.

[0071] The staff has previously wound a continuously connected strip of desiccant on a coil shaft 236. The strip of desiccant is a continuous connection of multiple independently packaged desiccants, which are produced by a desiccant production device. The strip of desiccant is pressed onto a cutting base plate 237 by a desiccant pressing roller 239 and a desiccant pressing plate in front of the desiccant pressing roller 239, and then runs to the position of a cutter 238 one by one. The cutter 238 cuts the strip of desiccant to form a single independently packaged desiccant, and the independently packaged desiccant after cutting is located on a desiccant support plate 240. Under the action of the cylinder, the desiccant support plate 240 moves close to the tray clamping mechanism 232 to facilitate the tray clamping mechanism 232 to clamp the desiccant.

[0072] In the specific bagging process, the packaging bag and the tray 8 are first loaded onto the bagging workbench 202 at the same time, and then the label is generated by the first labeling machine 228. The first labeling robot 229 labels the packaging bag and the tray 8. During this process, the desiccant storage mechanism 207 will cut the continuous strip-shaped desiccant into separate desiccant packages, and place the separate desiccant packages on the desiccant support plate 240; then the desiccant and humidity card are transported to the upper end surface of the tray 8 that has been labeled by the conveying robot 225, and then the tray 8 and the desiccant and humidity card thereon are transported together by the tray feeding mechanism 204 to the packaging bag whose bag mouth has been opened by the bag opening mechanism 203, and finally transported to the sealing machine for sealing.

[0073] During the whole bagging process, the packaging bags and the tray 8 can be loaded at the same time, the tray 8, the desiccant and the humidity card can be bagged at the same time, and the packaging bags and the tray 8 are labeled before bagging. The whole process has a high degree of automation and the modular design of the whole mechanism saves space and is convenient for maintenance. At the same time, the modules are reasonably distributed, so that the work efficiency can be greatly improved.

[0074] The tray packaging bag sealing detection mechanism 4 comprises a sealing detection frame 401, on which a tension detection mechanism 402 for detecting the sealing tensile strength of the sealing portion of the tray packaging bag 8 and an appearance detection mechanism 403 for detecting the appearance of the sealing portion of the tray packaging bag 8 are arranged, the tension detection mechanism 402 comprises two pulling components 404 arranged opposite to each other, the two pulling components 404 can act on the upper and lower end surfaces of the sealing portion of the packaging bag and make the upper and lower end surfaces have a tendency to move in opposite directions, and the appearance detection mechanism 403 comprises a detection camera 405 for taking pictures of the sealing portion of the tray packaging bag 8.

[0075] In this embodiment, the two pulling components 404 respectively include a first pulling cylinder 406 and a second pulling cylinder 407. The first pulling cylinder 406 and the second pulling cylinder 407 are arranged opposite to each other up and down. The piston rod ends of the first pulling cylinder 406 and the second pulling cylinder 407 are respectively connected to a first pulling suction cup mounting plate 408 and a second pulling suction cup mounting plate 409. The first pulling suction cup mounting plate 408 and the second pulling suction cup mounting plate 409 are respectively installed with pulling suction cups 410 that can be sucked on the upper end surface and the lower end surface of the sealing part of the packaging bag.
