[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-19 A multi-station hot pressing production line includes an automatic hot press 3. The automatic hot press 3 has a feeding device 1 on its inlet side. The feeding device 1 includes a first frame 101, on which several feeding components for the hot pressing production line are mounted. The first frame 101 also has a loading robot for the hot pressing production line that works in conjunction with the feeding components. The feeding device 1 has a receiving mechanism for the hot pressing production line on its outlet side. The feeding components provide film material to the automatic hot press 3. The loading robot places the sheet material to be hot-pressed onto the film material. The automatic hot press 3 hot-presses the sheet material through the film material. The receiving mechanism separates the film material from the sheet material, collects the sheet material, and winds up the film material. The automatic hot press 3 is an existing component, and its specific structure and principle are existing technologies, which will not be elaborated upon in this application.

[0020] The feeding assembly for the hot pressing production line includes two feeding sections disposed on the first frame 101, which are used to provide two films respectively separating the upper and lower surfaces of the sheet; The feeding section includes two first support frames 102 that are mounted on the first frame 101 by bolts and boat nuts. Each of the two first support frames 102 has a first notch 103. Each of the two first notches 103 contains a first limiting wheel 104. The inner sides of the two first limiting wheels 104 are rotatably connected by a first air shaft 107 through a bearing. The first air shaft 107 is used to carry the film roll. The outer ring of the bearing is interference-fitted with the inner wall of the first limiting wheel 104, and the inner ring of the bearing is interference-fitted with the outer surface of the first air shaft 107.

[0021] The first limiting wheel 104 has a first annular groove 105, the position of which corresponds to the position of the first notch 103, so as to limit the first limiting wheel 104 and prevent the first limiting wheel 104 from moving axially.

[0022] The first support frame 102 is threaded with a first handle bolt 106. One end of the first handle bolt 106 extends into the first annular groove 105. The first handle bolt 106 is used to cooperate with the first annular groove 105 to limit the first limiting wheel 104. After unscrewing the first handle bolt 106, the first limiting wheel 104 and the first air shaft 107 can be taken out. One of the first support frames 102 is bolted to the side of a first protective box 110. One end of the first limit wheel 104 is connected to a first gear 108 located inside the first protective box 110 by a key connection. The first gear 108 meshes with a second gear 109. The second gear 109 is connected to a magnetic powder clutch by a key connection. The magnetic powder clutch is bolted to the first protective box 110.

[0023] A first protective cover 111 is hinged to the first protective box 110. When closed, the first protective cover 111 works with the first protective box 110 to protect the first gear 108 and the second gear 109. When closed, the first protective cover 111 is fixed to the first protective box 110 with bolts to reduce the possibility of accidental opening.

[0024] The first frame 101 is provided with a number of second auxiliary rollers 112. The second auxiliary rollers 112 are used to provide a limit for the film material so that the film material is conveyed according to the corresponding trajectory. Both ends of the second auxiliary rollers 112 are rotatably connected to the first mounting plate through bearings. The first mounting plate is connected to the first frame 101 by bolts and boat nuts.

[0025] The feeding robot for the hot pressing production line includes a feeding device 2, which is mounted on a first frame 101. The feeding device 2 includes a second frame 201, with a support member connected to the bottom of the second frame 201 and mounted on the first frame 101. The second frame 201 is provided with a feeding section and a feeding section located below the feeding section. The feeding section includes a second linear module 210 connected to the second frame 201 by bolts and boat nuts. The moving end of the second linear module 210 is connected to a carrier plate 211, which is used to place a tray carrying sheet material.

[0026] The second frame 201 has two crossbeams 223 connected by bolts and boat nuts. The two crossbeams 223 are located on both sides of the carrier plate 211, and limiters are provided between the carrier plate 211 and the two crossbeams 223.

[0027] The limiting component includes a second slide rail 212 that is bolted to the crossbeam 223. A second slider 213 is slidably connected to the second slide rail 212. The second slider 213 is bolted to the carrier plate 211. The second slider 213 and the second slide rail 212 cooperate with each other to support and limit the carrier plate 211, thereby improving the stability of the carrier plate 211 when it moves.

[0028] The loading section includes a three-axis linear module 202 mounted on a second frame 201 by bolts and boat nuts. The moving end of the three-axis linear module 202 is connected to a first connecting plate 203 by bolts, and an adsorption component is provided on the first connecting plate 203.

[0029] The adsorption component includes several support beams 214 that are bolted to the first connecting plate 203. Several second support plates 215 are connected to the support beams 214 by bolts and wing nuts. Several vacuum suction cups 205 are provided on the second support plates 215. The vacuum suction cups 205 are existing components, and their specific installation methods and air circuit connections are all existing technologies, which will not be described in detail in this application.

[0030] The first connecting plate 203 is also provided with a detection unit, which includes a third support plate 216 that is bolted to the first connecting plate 203. A detection sensor 217 and a fixing seat 218 located below the detection sensor 217 are bolted to the third support plate 216.

[0031] A D-axis 219 is connected to the fixed base 218 via a linear bearing. A detection plate 220 is bolted to the D-axis 219. A detection sensor 217 is located on the lifting trajectory of the detection plate 220. A pressure rod 206 is bolted to the bottom end of the D-axis 219. A spring 221 located below the fixed base 218 is sleeved on the outer surface of the D-axis 219. During the descent, the pressure rod 206 first contacts the sheet material. The pressure rod 206 stops descending, and then the vacuum suction cup 205 continues to descend, causing the detection plate 220 to move towards the detection sensor 217. When the detection sensor 217 detects the detection plate 220, it indicates that the vacuum suction cup 205 has contacted the sheet material. During the process of the vacuum suction cup 205 releasing the sheet material, the force of the spring 221 pushes the pressure rod 206, so that after the vacuum suction cup 205 releases the suction of the sheet material, the force of the spring 221 can push the sheet material down through the pressure rod 206 so that the sheet material can be removed from the vacuum suction cup 205.

[0032] The bottom of the fixed base 218 is connected to the limiting sleeve 222 by bolts. The limiting sleeve 222 is located between the spring 221 and the pressure rod 206. The limiting sleeve 222 has a limiting hole that matches the cross section of the D-axis 219, thereby limiting the D-axis 219 and preventing it from rotating during the lifting and lowering process.

[0033] The support includes two first support plates 207 connected to the first frame 101 by bolts and boat nuts. A first slide rail 208 is bolted to the top of the first support plate 207. Several first sliders 209 are slidably connected to the first slide rail 208. The first sliders 209 are connected to the bottom of the second frame 201 by bolts and boat nuts.

[0034] The side of the first support plate 207 is connected to the limit plate 204 by bolts. The limit plate 204 is connected to the second frame 201 by bolts and boat nuts. After loosening the bolts between the limit plate 204 and the second frame 201, the second frame 201 can be moved horizontally to adjust the horizontal position of the second frame 201. After tightening the bolts, the position of the second frame 201 can be fixed.

[0035] Currently, manual material loading is commonly used in the industry. Manual handling of sheet materials is labor-intensive and has poor operational safety. Furthermore, manual material loading has poor positioning accuracy and an unstable loading rhythm.

[0036] This application utilizes a loading robot in a hot pressing production line. The feeding unit places a pallet containing sheet material, and the sheet material is picked up by the loading unit and placed in the corresponding position. This reduces manual intervention and improves efficiency and safety. Since the second linear module 210 can drive the carrier 211 to move horizontally, the carrier 211 can move between two horizontal workstations. In conjunction with the second support plate 215 driven by the three-axis linear module 202, the loading of sheet material at both workstations can be completed.

[0037] The material receiving mechanism for the hot pressing production line includes a material receiving device 4, which includes a third frame 401. The third frame 401 is equipped with a separation component, a sheet material collection structure 402, and two film material receiving components. The film material receiving components include two eighth support plates 419 connected to the third frame 401 by bolts and boat nuts. Each of the two eighth support plates 419 has a second notch 409, and each of the two second notches 409 contains a second limiting wheel 410. The two second limiting wheels 410 are rotatably connected by a second air shaft 413 through a bearing. The second air shaft 413 is interference-fitted with the inner ring of the bearing, and the outer ring of the bearing is interference-fitted with the second limiting wheel 410.

[0038] The second limiting wheel 410 has a second annular groove 411, the position of which corresponds to the position of the second notch 409. A fixing member is provided between the eighth support plate 419 and the second annular groove 411. The fixing member is used to limit the second limiting wheel 410. The fixing member includes a second handle bolt 412 threadedly connected to the eighth support plate 419. One end of the second handle bolt 412 extends into the second annular groove 411. The second handle bolt 412 and the second annular groove 411 cooperate with each other to limit the second limiting wheel 410. After the second handle bolt 412 is loosened and separated from the second annular groove 411, the second air shaft 413 and the second limiting wheel 410 can be taken out from the second notch 409.

[0039] One of the eighth support plates 419 has a second protective box 407 bolted to its side. A second motor 406 is bolted to the outer side of the second protective box 407. The output shaft of the second motor 406 extends into the second protective box 407 and is connected to a third gear 414. One end of the second air shaft 413 is also located inside the second protective box 407 and is connected to the third gear 414. The two third gears 414 mesh, and the second motor 406 and the third gear 414 cooperate to drive the second air shaft 413 to rotate in order to wind up the membrane material, thereby providing the necessary power for the membrane material to move the sheet.

[0040] A second protective cover 408 is hinged to the second protective box 407. When closed, the second protective cover 408 cooperates with the second protective box 407 to protect the third gear 414. When closed, the second protective cover 408 is fixed to the second protective box 407 with bolts to reduce the possibility of accidental opening.

[0041] The sheet collection structure 402 includes a collection box 4022 and several fourth support plates 4021 located on both sides of the collection box 4022. The fourth support plates 4021 are connected to the third frame 401 by bolts and boat nuts. The top of the fourth support plate 4021 has a slot, and a support rod 4023 is inserted into the slot. The support rod 4023 is welded to the side of the collection box 4022. The support rod 4023 and the fourth support plate 4021 cooperate to support the collection box 4022. The collection box 4022 can be removed by pulling it upward, which makes it easier to take out the sheet collected in the collection box 4022.

[0042] The separation assembly includes two seventh support plates 415 connected to the third frame 401 by bolts and boat nuts. A first support roller 416 and a second support roller 417 are rotatably connected between the two seventh support plates 415 via bearings. The outer ring of the bearing is interference-fitted with the seventh support plate 415, and the inner ring of the bearing is interference-fitted with the first support roller 416. A separator plate 418 is also bolted between the two seventh support plates 415. When the two membrane materials pass through the first support roller 416 and the second support roller 417, their paths are changed, causing the two membrane materials to separate. The sheet falls into the collection box 4022 after passing over the top of the separator plate 418.

[0043] It also includes an auxiliary mechanism 404, which includes a fifth support plate 4041 connected to the third frame 401 by bolts and boat nuts. The top of the fifth support plate 4041 is connected to two sixth support plates 4042 by bolts. A lower roller 4043 is connected between the two sixth support plates 4042 by a bearing housing and a bearing. The outer ring of the bearing is connected to the bearing housing, and the bearing housing is connected to the sixth support plate 4042 by bolts. The inner ring of the bearing is interference-fitted with the lower roller 4043. A first motor 4044 is bolted to the fifth support plate 4041, and the output shaft of the first motor 4044 is connected to the lower roller 4043 by a coupling.

[0044] The first motor 4044 drives the lower roller 4043 to rotate. During rotation, the lower roller 4043 can cooperate with the upper roller 4047 to provide additional power to the membrane material. The auxiliary mechanism 404 is optional. If the length of the membrane material between the collection box 4022 and the second air shaft 413 is long, the auxiliary mechanism 404 can be set to provide additional power. Figure 19 As shown, if the length of the membrane material between the collection box 4022 and the second air shaft 413 is not long, it can be wound up by the second support roller 417, and the auxiliary mechanism 404 does not need to be added.

[0045] Each of the two sixth support plates 4042 has a limiting groove on its top. A slide block 4046 is slidably connected within each limiting groove. Slide grooves are provided on both sides of each slide block 4046, and these grooves cooperate with the inner walls of the limiting grooves to limit the movement of the slide block 4046, allowing it to only move up and down. An upper roller 4047, located above the lower roller 4043, is rotatably connected to the two slide blocks 4046 via a bearing. The outer ring of the bearing is interference-fitted with the slide block 4046, and the inner ring of the bearing is connected to the upper roller 4047. The top of each of the six support plates 4042 is bolted to a cylinder 4045. The top of the slide block 4046 is provided with a T-slot. The piston rod of the cylinder 4045 extends into the T-slot, and two nuts are threaded onto the piston rod of the cylinder 4045. The two nuts are located in the T-slot and on the top of the slide block 4046, respectively. The two cylinders 4045 are synchronously raised and lowered. The synchronous raising and lowering control method is existing technology. Several second connecting rods 4048 are bolted between the two sixth support plates 4042.

[0046] The third frame 401 is provided with several first auxiliary rollers 405. The first auxiliary rollers 405 are used to provide a limit for the film material so that the film material is conveyed according to the corresponding trajectory. Both ends of the first auxiliary rollers 405 are rotatably connected to second mounting plates through bearings. The second mounting plates are connected to the third frame 401 through bolts and boat nuts.

[0047] The material collection process in hot pressing production lines often uses manual separation. During manual separation, operators need to manually separate the hot-pressed film material from the sheet material, which is labor-intensive and has low collection efficiency. This application uses a membrane material take-up assembly to wind up two membrane materials separately. Under the action of the separation assembly, the two membrane materials can be separated. After the two membrane materials are separated, the sheet located between the two membrane materials is also separated from the membrane materials and finally falls into the sheet collection structure 402 for collection, thereby realizing the automatic separation of membrane materials and sheets, the winding of membrane materials, and the collection of sheets.

[0048] The first frame 101, the second frame 201, and the third frame 401 are all made of aluminum profiles. The control of each component in this application relies on the existing PLC control system. The various sensors, solenoid valves, drivers, and circuit connections required for the operation of the PLC control system are all prior art. The specific circuit layout and program writing can be configured according to the actual equipment parameters. This is prior art and will not be described in detail in this application. When using, refer to Figure 18 In the figure, point B is marked as the film roll set on the first air expansion shaft 107, which is in the released state during use; point A is marked as the film roll set on the second air expansion shaft 413, which is in the wound state during use; and point C is marked as the feeding position of the sheet. Specifically, after the membrane material is drawn out from the membrane roll, it is limited by the second auxiliary roller 112 so that one membrane material passes through the sheet feeding area of ​​the feeding device 2 and the other membrane material passes through the non-feeding area of ​​the feeding device 2. After the membrane material passes through the feeding area of ​​the feeding device 2, the feeding device 2 places the sheet material on the membrane material. Then the sheet material is limited between the two membrane materials and carried by the two membrane materials into the automatic hot press 3. The automatic hot press 3 performs hot pressing. During the hot pressing process, the membrane material protects the sheet material and the automatic hot press 3. After hot pressing, the membrane material and the sheet material move towards the collection box 4022. At this time, the two membrane materials pass through the first support roller 416 and the second support roller 417 respectively and are wound up by the second air expansion shaft 413 respectively, so that the two membrane materials separate. The separation point of the two membrane materials is located above the collection box 4022, so that the sheet material falls into the collection box 4022 for collection during the separation process of the two membrane materials. The feeding process of the feeding device 2 for the sheet is as follows: the tray carrying the sheet is placed in the carrier plate 211, and the carrier plate 211 can move linearly to adjust its position under the action of the second linear module 210. The three-axis linear module 202 and the first connecting plate 203 cooperate to drive the vacuum suction cup 205 to move along the XYZ three-axis direction, so that the vacuum suction cup 205 can pick up the sheet in the tray and move it onto the film to complete the feeding.
