[0062] In this embodiment, the high-frequency heat sealing machine 71 is used to high-frequency weld the bottom surface of the bed sore bed, the massage air bag, and the bed sore bed contact surface. The power of the high-frequency heat sealing machine is 6.5 KW, the air pressure used is 6.5-7.5 KG, the preheating time is 8-12 minutes, the working frequency is 40.5 MHz, the sealing radio frequency (RF) power is 30 W, and the heat sealing time is set to 4.5-5.5 seconds.

[0063] In this embodiment, the high-frequency heat sealing machine is provided with a lower mold heating assembly 75 and an upper mold heating assembly 76 for melting the stacked bed sore prevention bed 63. One side of the high-frequency heat sealing machine is provided with a conveying table 73 for placing the stacked materials of the bed sore prevention bed. The conveying table is provided with a conveying track 74 connected to the high-frequency heat sealing machine, which can convey the stacked materials to the upper end of the lower mold heating assembly 75. The front side of the high-frequency heat sealing machine is provided with a finished product table 77, and the two sides of the high-frequency heat sealing machine are provided with grating assemblies 78 to prevent personnel from entering during equipment operation. The two sides of the high-frequency heat sealing machine are provided with execution switches 79, which need to be operated by two people at the same time to operate.

[0064] Before operation, lay the anti-skid pad 87 on the finished product table, and fix two side-turning air cushions 120 on the left and right sides of the anti-skid pad 87. After fixing, turn over the anti-skid pad 87 for standby. Place the bed sore bed bottom surface 65 on the upper end of the conveying table 73, with the concave surface of the bed sore bed bottom surface 65 facing upward. Place eight massage air bags 67 in two columns into the recesses of the bed sore bed bottom surface 65, and pass the air inlet pipe 70 through the hole of the bed sore bed bottom surface 65. Lay the bed sore bed contact surface 66 on the upper end of the bed sore bed bottom surface 65, with the convex surface of the bed sore bed bottom surface 65 facing upward. Lay the insulating layer 72 on the stacked materials before feeding the mattress to the high-frequency heat sealing machine, which can prevent the materials from being damaged by short circuit and breakdown. Start the switch 79, and the conveying table 73 feeds the stacked materials to the upper end of the lower mold heating assembly 75. The upper mold heating assembly 76 is connected to the signal and is pressed down.

The operator places the stacked materials on the anti-skid pad 87 on the finished product table 77 for cooling, which takes about 15-25 seconds. The operator takes the next bed sore bed bottom surface 65 and bed sore bed contact surface 66 from the conveying table 73, and stacks them. Then, the operator takes the insulating layer 72 from the finished product table 77 and lays it on the conveying table 73 for recycling production. After fixing the pressed materials and the anti-skid pad 87, the operator takes the air bag group 68 and sticks it to the bed sore bed assembly product. Multiple pipe joints 69 are installed on the side of the air bag group 68 for connecting each air bag.

[0065] In this embodiment, the assembly of the hip frame assembly and the leg frame assembly is completed on the second workbench 97. One side of the second workbench is provided with a leg frame assembly carrier 98, and the other side of the second workbench is provided with a bed plate carrier 99. Different specifications of lean pipe are used to form the leg frame assembly 23. After locking, the finished product is placed on the carrier 98 for standby. The leg frame assembly carrier 98 is composed of a long nylon block, which has multiple grooves to limit the leg frame assembly 23 and prevent scratching. After the hip frame assembly 22 is assembled, it can be directly placed on the second workbench 97 for standby due to its small area. The bed plate carrier 99 has a lifting function. The elastic force pulls the moving pulley, which drives the lifting platform to move downward through the traction rope, and the load bed plate surface sinks. The bed plate surface is taken out and returned to its original position. This can avoid bending over for work and maintain a horizontal carrying operation. The bed plate has multiple direction grooves for air bag and air pipe arrangement. When the base structure is conveyed to this station, the leg frame assembly 23 on the leg frame assembly carrier 98 is locked on the upper end of the second connecting frame 9. Two frame connecting pieces 24 are taken to fix the leg frame assembly 23 and the hip frame assembly 22. Six bed plates are taken out from the bed plate carrier 99 and are fixed to the leg frame assembly 23 and the hip frame assembly 22.

[0066] In this embodiment, the assembly of the back frame assembly and the connecting frame assembly is completed on the third workbench 101. The third workbench is provided with a back frame assembly carrier 102 on one side and a bed plate carrier 103 on the other side. The back frame assembly 20 is composed of different specifications of lean pipes. After locking, the finished product is placed on the back frame assembly carrier 102 for suspension. The back frame assembly carrier 102 is composed of a long strip of nylon blocks, which has a plurality of grooves built-in to limit the back frame assembly 20 and prevent scratches caused by collision. The connecting frame assembly 21 is directly placed on the third workbench 101 for standby after the frame structure is assembled. The bed plate carrier 103 has the same structure as the bed plate carrier 103. When the transplanting bed semi-finished product of the previous process is transported to this station, the connecting frame assembly 21 on the third workbench 101 is locked on the first connecting frame 6, the back frame assembly 20 is placed at the front end of the base structure, the lifting cylinder is raised to lock it inside the back frame assembly 20, and two frame connecting pieces 24 are used to connect the back frame assembly 20 and the connecting frame assembly 21. Five bed plates are taken out from the bed plate carrier 103 and buckled into the back frame assembly 20 and the connecting frame assembly 21 for fixation.

[0067] The manual setting switch 82 is set at 12V voltage, and the first electric cylinder 5 and the second electric cylinder 8 are synchronously controlled through the wire harness 112. The stroke is 0-250mm. The manual setting switch 82 is connected to the air pump 84 through the wire harness. The air pump 84 has three-way input and output air sources, including the cylinder air pipe 115, the massage air pipe group 116, and the air bag air pipe 117. The cylinder air pipe 115 controls the cylinder 25, which is actuated at the same time with the first electric cylinder 5 and the second electric cylinder 8, to actuate the transplanting bed 119 into a semi-sitting and lying mode. The massage air pipe group 116 controls the air fluctuation of the anti-bedsore bed 63, and is connected to the side-rolling air cushion 120, the massage air bag 67, and the air bag group 68. When the left side-rolling air cushion 120 is inflated, the anti-bedsore bed 63 rolls the patient to the right side, the left four groups of massage air bags 67 are actuated, the air bag body of the massage air bag 67 is inflated and contracted to achieve local massage effect and promote blood circulation, and the right side has the same method. The left side-rolling air cushion 120 is deflated, and the right side-rolling air cushion 120 is inflated. The pillow is usually placed on the upper end of the air bag group 68, and the pressure of the pillow against the neck is changed by air contraction. The automatic setting switch 81 is consistent with the manual setting switch 82, and the memory function is added to set the side-rolling time and set multiple side-rolling actions. The automatic setting switch 82 is connected to the pressure distribution control box 86 through the wire harness 118, and the air sources of the air pump 84 are controlled by the pressure distribution control box 86. The transplanting bed cannot perform the side-rolling function when it is actuated into a semi-sitting and lying mode, and the anti-bedsore bed 63 and the eight groups of massage air bags 67 can be freely set to fluctuate. The function setting is mainly to avoid the long-term pressure on the local tissue of the long-term bedridden patient, which causes continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis.
