[0026] Specifically, the heating device 3 includes a driving component and a high-frequency motor 306 disposed on the output end of the driving component. A heating coil 305 is fixedly installed at the front end of the high-frequency motor 306 and above the mold transfer device 4. The driving component includes a rod motor 311. The output end of the rod motor 311 is fixedly connected to a high-frequency machine base plate 304. The top of the high-frequency machine base plate 304 is fixedly installed with the high-frequency machine 306. Multiple sets of three-column 302 are slidably connected on the high-frequency machine base plate 304. A sensor mounting plate 310 is disposed on one side of the high-frequency machine base plate 304. Two sets of origin sensors 309 are disposed on the sensor mounting plate 310. A three-column fixing plate 308 is disposed between the two sets of three-column 302 on the same side of the high-frequency machine base plate 304. A limit plate 307 is fixedly connected between the two sets of three-column fixing plates 308.

[0027] refer to Figure 2 The product needs to be stacked on mold 404. The worker places mold 404 on mold transfer device 4, which transports mold 404 to below heating coil 305. When mold 404 is directly below heating coil 305, rod motor 311 starts, driving high frequency machine 306 downwards along the extension direction of column 302 via high frequency machine base plate 304. High frequency machine 306 drives heating coil 305 downwards. When rod motor 311 drives high frequency machine base plate 304 to descend to the set lowest point position along the extension direction of column 302, high frequency machine base plate 304 triggers the origin sensor at the bottom of sensor mounting plate 310. At this time, heating coil 305 is placed on mold 404, and mold 404... Heating is performed to solidify the product on the mold 404. When the set temperature and time are reached, the rod motor 311 rises through the high-frequency machine base plate 304 until the high-frequency machine base plate 304 triggers the origin sensor 309 at the top of the sensor mounting plate 310. At this time, the heating coil 305 disengages from the mold 404. The limiting plate 307 and the column fixing plate 308 effectively prevent the high-frequency machine base plate 304 from disengaging from the column 302. The bottom of multiple columns 302 are fixedly installed with bases 301, and the heating device 3 is fixedly installed through the bases 301. The high-frequency machine base plate 304 is equipped with linear bearings 303 that correspond one-to-one with the number and position of the columns 302 to reduce the friction when the columns 302 move.

[0028] Specifically, the pressure application device 2 includes a pressing base plate 206, a servo press 201 installed below the pressing base plate 206, and a moving part disposed at the output end of the servo press 201. The top of the moving part penetrates through the pressing base plate 206, and a pressure sensor 210 is fixedly installed at one end of the moving part penetrating the pressing base plate 206. A mold pressing block 211 is installed below the pressure sensor 210. The pressure application device also includes a mounting component, which includes a press mounting plate 202 disposed on the end face of the servo press 201. Multiple sets of upright columns 203 are provided, and the tops of the multiple sets of upright columns 203 are fixedly connected to the press-fit base plate 206; the moving parts include multiple sets of guide columns 208 that slide through the press-fit base plate 206, and the bottoms of the multiple sets of guide columns 208 are fixedly connected to the same floating head joint mounting plate 205. The servo press is fixedly connected to the floating head joint mounting plate 205 through the floating head joint 204. The tops of the multiple sets of guide columns 208 are fixedly connected to the same set of guide column mounting plates 209, and the bottoms of the guide column mounting plates 209 are fixedly installed with the pressure sensor 210.

[0029] refer to Figure 3 When the mold transfer device 4 pulls the mold 404 directly below the mold pressing block 211, the servo press 201 drives the floating head joint mounting plate 205 downward through the floating head joint 204. The floating head joint mounting plate 205 drives the guide column mounting plate 209 downward through the guide column 208. The guide column mounting plate 209 drives the mold pressing block 211 downward, causing the mold pressing block to press down on the product on the mold 404 and expose the nut on the mold 404. The pressure sensor 210 detects the pressure between the mold pressing block 211 and the product. When the pressure detected by the pressure sensor 210 reaches the set pressure, the floating head joint 204 of the servo press 201 stops moving, preventing the guide column mounting plate 201 from moving downward. 9. Continue to move downwards and maintain the set pressure. Then, rotate the nut on the mold 404 through the bolt tightening device to lock the mold 404. After the mold 404 is locked, the servo press 201 pushes the guide column mounting plate 209 upwards, so that the mold pressing block 211 is separated from the mold 404. There are four sets of guide columns 208. Linear bearings 207 corresponding to the position and number of guide columns 208 are fixedly installed on the pressing base plate 206. The guide columns 208 and linear bearings 207 are slidably connected to reduce the friction of the guide column 208 movement. The pressure sensor model is DYHX-003. At the same time, the mold pressing block 211 is provided with a through hole for the sleeve 112 to move.

[0030] Specifically, the bolt tightening device 1 is positioned above the pressure application device 2. The bolt tightening device 1 is equipped with a Y-axis linear module 107 and a connecting plate 105 slidably mounted on the Y-axis linear module 107. A tightening element is mounted on the connecting plate 105, which sequentially passes through the guide column mounting plate 209, the pressure sensor 210, and the mold pressure block 211. The bolt tightening device 1 also includes multiple sets of uprights 101. The bottom of each set of uprights 101 is fixedly connected to the press-fit base plate 206, and the top of each set of uprights 101 is fixedly connected to a set of upright base plates 102. The upright base plates 102 are located above the guide column mounting plate 209, and guide rail plates are fixedly connected to the upright base plates 102. 103, A linear guide rail 104 is fixedly installed on the guide rail plate 103. The end of the connecting plate 105 away from the Y-axis linear module 107 is slidably connected to the linear guide rail 104. The Y-axis linear module 107 is fixedly installed to the column base plate 102 through the module fixing plate 108. The tightening component includes an electric screwdriver 106 installed on the connecting plate 105. An adapter rod 111 is installed at the output end of the electric screwdriver 106. The bottom of the adapter rod 111 passes through the column base plate 102, the guide column mounting plate 209, the pressure sensor 210, and the mold pressing block 211 in sequence and extends to the bottom of the mold pressing block 211. A sleeve 112 is fixedly installed at the end of the adapter rod 111 that extends to the bottom of the mold pressing block 211.

[0031] refer to Figure 4 When the servo press 201 reaches the preset pressure, the Y-axis linear module 107 drives the electric screwdriver 106 to move upward via the connecting plate 105. This causes the electric screwdriver 106 to drive the sleeve 112 downward via the adapter rod 111. The sleeve 112 passes sequentially through the guide post mounting plate 209, the pressure sensor 210, and the mold pressing block 211 until it is fitted onto the nut of the mold 404. At this point, the electric screwdriver 106 rotates according to the set torque, thereby causing the sleeve 112 to rotate the nut on the mold 404, thus locking the mold 404. After locking, the Y-axis linear module 107 moves downward. The wire module 107 drives the electric screwdriver 106 to move upward through the connecting plate 105, so that the sleeve 112 is disengaged from the nut. After the sleeve 112 and the mold pressure block 211 are both disengaged from the mold 404, the transfer device sends the mold 404 out for manual removal. The linear guide rail 104 can provide guidance for the connecting plate 105. The electric screwdriver 106 is installed on the connecting plate 105 through the electric screwdriver fixing plate 110, and the two sides of the electric screwdriver fixing plate 110 are fixedly connected to the connecting plate 105 with reinforcing ribs 109. The sleeve 112 is adapted to the mold on the mold 404.

[0032] Specifically, the mold transfer device 4 includes an X-axis linear module 402 installed on the pressing base plate 206 and located below the mold pressing block 211, and a mold fixing plate 406 slidably disposed on the X-axis linear module 402. A mold adapter plate 405 is fixedly connected to the mold fixing plate 406, and a mold 404 is installed on the mold adapter plate 405. The mold transfer device 4 also includes a first pressure block 401 and a second pressure block 403 respectively disposed on both sides of the X-axis linear module 402.

[0033] refer to Figure 5 The mold 404 is placed manually on the mold adapter plate 405. The X-axis linear module 402 drives the mold adapter plate 405 to move back and forth in the X direction through the mold fixing plate 406. When the mold pressure block 211 moves downward, the pressure block 401 and the pressure block 403 provide support for the mold fixing plate 406, so as to avoid excessive pressure from damaging the X-axis linear module 402.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
