[0001] This invention belongs to the field of board foaming technology, and specifically relates to a six-station roller-type board foaming line and its usage method. Background Technology

[0002] Currently, with the rapid development of the lithium battery industry, the production efficiency requirements of the foaming production lines used in it are also constantly increasing. The existing foaming production lines have a low degree of automation and high labor intensity for workers, which is not conducive to improving the overall production efficiency of the production line and urgently needs to be improved. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a six-station roller-type foaming line for sheet materials and its usage method. The specific technical solution is as follows:

[0004] A six-station roller-type sheet foaming line, comprising:

[0005] Two support frames are arranged vertically opposite to each other.

[0006] A roller frame is horizontally mounted on top of two support frames. The roller frame includes a horizontally arranged main shaft. The ends of the main shaft are rotatably connected to the top of the corresponding support frame through support shaft seats. A regular hexagonal turntable is axially fixedly connected to the main shaft.

[0007] A drive gear is axially fixed to the end face of one of the regular hexagonal turntables, and the drive gear is used to drive the roller frame to rotate circumferentially.

[0008] The foaming mold frame is composed of an upper template and a lower template hinged together. The ends of the upper template are respectively fixedly connected to the edges of the corresponding regular hexagonal turntable.

[0009] A mold-connecting device is used to support the lower mold plate to realize mold opening and mold closing. The mold-connecting device is horizontally arranged below one side of the roller frame.

[0010] A locking device is used to unlock and lock the upper and lower templates; the opening and closing angle of the locking device is when the foaming mold frame is rotated to a 60° angle with the horizontal plane.

[0011] A punching and filling robot is used to punch holes in the sheet material placed in the foaming mold frame and fill it with foaming material; the punching and filling robot is suspended above the mold receiving device;

[0012] A bubble-blocking robot is used to grasp bubble-blocking plugs to block the filling holes punched by the drilling and filling robot on the plate. The bubble-blocking robot and the drilling and filling robot share the same guide rail that is horizontally suspended on the outside of the top of the support frame, and the bubble-blocking angle, the drilling angle and the filling angle are all 50° with the horizontal plane.

[0013] A loading and unloading robot is used to pick up and place sheet metal horizontally, and the loading and unloading robot is horizontally arranged outside the mold receiving device.

[0014] Furthermore, six positioning holes are evenly spaced circumferentially opened along the outer end face edge of the drive gear; two positioning cylinders are longitudinally offset on the support frame on the same side as the drive gear. When the piston rod of the lower positioning cylinder passes through the positioning hole at the lowest point of the drive gear, the foaming mold frame forms a 60° angle with the horizontal plane; when the piston rod of the upper positioning cylinder passes through the positioning hole rotated from the lowest point of the drive gear, the foaming mold frame forms a 50° angle with the horizontal plane.

[0015] Furthermore, circulating water pipes are evenly distributed inside the upper and lower templates, and the circulating water pipes are connected to an external mold temperature controller through a circulating water integrated frame axially fixed to the end face of another hexagonal turntable.

[0016] The circulating water integrated frame includes a regular hexagonal water pipe. Two regular hexagonal water pipes are axially connected and superimposed through multiple circumferentially evenly arranged connecting columns. Two valves are arranged opposite each other at the same position on the edges of the two regular hexagonal water pipes. The two valves on the same edge of one of the regular hexagonal water pipes are respectively connected to the inlet of the circulating water pipe in the upper template and the lower template through water pipes. The two valves at the same position on the other regular hexagonal water pipe are respectively connected to the outlet of the circulating water pipe in the upper template and the lower template through water pipes.

[0017] The end of the spindle is hollow, and a rotary joint is axially arranged inward on the end face of the spindle. The water inlet and outlet pipes of the external mold temperature controller are axially connected in parallel inside the rotary joint. Water inlets are radially symmetrically arranged on the two regular hexagonal water pipes, and the two water inlets are respectively connected to the end of the corresponding spindle through water pipes.

[0018] Furthermore, the mold-receiving device includes a linkage shaft, and mold-receiving arms are axially symmetrically fixedly connected to the ends of the linkage shaft. The mold-receiving arms are rotatably supported and connected by a mold-receiving drive mechanism.

[0019] The end faces of the lower template are vertically and symmetrically connected with rollers. A safety bar is horizontally arranged on one side of each roller, and the outer diameter of the safety bar is smaller than the outer diameter of the roller. When the mold receiving arm rotates to the highest point of mold receiving, it contacts and supports the roller on the same side.

[0020] Furthermore, a fixed template strip is detachably fixed at one end of the top surface of the lower template along its short side; fixed template segments are detachably fixed at equal intervals along the long side of the outer side of the top surface of the lower template; a movable template strip is slidably placed on the inner side of the top surface of the lower template along its long side, and the movable template strip is pushed by a template strip driving mechanism; steel plates are equally spaced and parallel to each other on the top surface of the lower template near the fixed template segments, and the steel plates are parallel to the fixed template segments, and the top surface of the steel plates is flush with the top surface of the lower template; a magnetic template strip is magnetically attracted to the steel plate, and the magnetic template strip is parallel to the fixed template strip, and the length of the magnetic template strip is adapted to the width of the plate.

[0021] Furthermore, the plate has a hollow, stepped structure, and is assembled from a lower plate and an upper plate, with the size of the lower plate being smaller than that of the upper plate. The fixing strip, fixing segment, moving strip, and magnetic strip are respectively tightly fitted to the corresponding side of the lower plate, and the bottom surface of the lower plate is attached to the top surface of the lower template.

[0022] Furthermore, the template driving mechanism includes a scissor fork, with a first slide block vertically connected to the bottom end of the pin shaft of the scissor fork. A first slide rail is horizontally slidably connected to the bottom of the first slide block. An installation groove is formed on one side of the top surface of the lower template along its short side, and the first slide rail is embedded in the installation groove. One side of the scissor fork's connecting rod end is hinged to the end of the corresponding movable template, and the lower part of the other side's connecting rod end is hinged to a second slide block. The bottom of the second slide block is horizontally slidably connected to a second slide rail, and the second slide rail is fixedly connected along the long side of the corresponding lower template. A push plate is vertically suspended on one end face of the second slide block, and a driving cylinder is horizontally opposite to the two push plates. The driving cylinder is fixedly connected to the long side of the corresponding lower template, and the piston rod of the driving cylinder is vertically connected to the corresponding push plate.

[0023] Furthermore, the locking device includes a movable locking module, and the movable locking module is symmetrically arranged laterally on the long side of the upper template. The movable locking module includes a linkage straight plate, which is laterally limited and slidably connected to the corresponding long side of the upper template. Multiple suspension plates are fixedly arranged at equal intervals on the outer surface of the linkage straight plate. A pin is vertically connected to the bottom of the inner surface of the suspension plate, and a roller is rotatably connected to the end of the pin.

[0024] The fixed locking module is provided with a plurality of fixed locking modules arranged at equal intervals on the long side of the lower template. The fixed locking module includes a fixing plate, which is fixedly attached to the long side of the lower template. The outer surface of the fixing plate is provided with a Z-shaped guide groove, and the width of the guide groove is the same as the outer diameter of the roller.

[0025] The opening and closing locking mechanism is provided symmetrically on both short sides of the upper template. Each mechanism includes a mounting plate, which is inclined to the corresponding support frame at a 60° angle. A speed reducer is vertically mounted on the center of the outer surface of the mounting plate. A motor is longitudinally connected to the power input end of the speed reducer, and rotating shafts are symmetrically connected to the bidirectional power output ends of the speed reducer. Retractable impact members are symmetrically and vertically arranged at the ends of the rotating shafts. These impact members are used to impact the corresponding ends of the linkage plate.

[0026] Furthermore, the linkage straight plate is provided with multiple guide holes that are equally spaced laterally, and a suspension plate is provided in the middle between two adjacent guide holes; the long side of the foaming mold frame of the board is fixedly provided with mounting blocks with an L-shaped cross-section at equal intervals laterally, and a T-shaped limiting block is vertically connected to the front of the vertical part of the mounting block. The vertical part of the limiting block is laterally slidably sleeved with the corresponding guide hole, and the top surface of the horizontal part of the mounting block is laterally slidably attached to the bottom surface of the linkage straight plate; when the roller rolls into or out of the guide groove, the vertical part of the limiting block abuts against the end of the corresponding guide hole.

[0027] The usage method of a six-station roller-type foaming line for sheet materials includes the following steps:

[0028] Step S1: The sheet metal is positioned and stacked on one side of the loading and unloading robot.

[0029] Step S2: First, the foaming mold frame is rotated to a 60° angle with the horizontal plane to open the mold. The mold receiving arm is rotated to the highest point of mold receiving and contacts the roller support corresponding to the end face of the lower mold plate. Then, one of the impact members of the opening and closing locking mechanism impacts the end of the corresponding linkage straight plate to unlock the foaming mold frame. At the same time, the mold receiving arm drives the lower mold plate to rotate downward to a horizontal position.

[0030] Step S3: First, the loading and unloading robot picks up the positioned sheet material and moves horizontally to above the positioning edge formed by the fixed mold strip and fixed mold segment on the top surface of the foaming mold frame. Then, the loading and unloading robot lowers the sheet material and returns to its original position.

[0031] Step S4: First, the moving mold bar moves toward the fixed mold section under the action of the driving cylinder to position and press against the plate. Then, the magnetic mold bar is manually applied to position the plate.

[0032] Step S5: First, the mold receiving arm rotates upward to the mold closing position. Another impactor of the opening and closing locking mechanism impacts the end of the corresponding linkage straight plate to lock the foaming mold frame. Then, the mold receiving arm rotates down to return to its original position.

[0033] Step S6: First, the foaming mold frame rotates 10° in the same direction to a 50° angle with the horizontal plane, which is the angle position for drilling, filling, and plugging the board. Then, the drilling and filling robot moves horizontally to the pre-reserved opening position of the product and starts its own drilling electric drill to perform drilling operations. After the filling hole is opened, it starts its own filling gun head to fill the foaming material. After the filling is completed, the drilling and filling robot moves laterally to the end of the guide rail. During the drilling and filling process, the bubble plugging robot picks up the bubble plug and waits beside it. After the filling is completed, it immediately moves to the filling hole to plug the bubble.

[0034] Step S7: First, the foaming mold frame that has completed the above steps is rotated 50° in the same direction to a horizontal state. The board inside the foaming mold frame enters the foaming and curing time. At this time, the next foaming mold frame is exactly at a 60° opening angle with the horizontal plane. Then, the mold receiving arm rotates to the highest point of mold receiving, and the impact member of the opening and closing locking mechanism impacts and unlocks this foaming mold frame. At the same time, the mold receiving arm drives the lower mold plate to rotate downward to a horizontal position.

[0035] Step S8: First, the moving mold strip returns to its original position under the action of the drive cylinder. At the same time, the magnetic mold strip is manually removed. Then, the loading and unloading robot moves horizontally to the position of the lower mold, descends and picks up the foamed board, and then moves horizontally to place the foamed board onto the unloading conveyor line. The foaming of the board is completed.

[0036] The beneficial effects of this invention are:

[0037] This invention employs a horizontal axis vertical rotation structure, with two hexagonal turntables rotating around the main shaft, driven by a drive gear. Six foaming mold frames are installed between the two hexagonal turntables of the roller frame, forming six circulating foaming stations, saving production time and costs. The mold-connecting device and mold-locking device work together to efficiently complete the opening and closing operations of the foaming mold frames. The included punching and filling robot performs punching and filling on the same robot, ensuring the coplanarity of the punching and filling angles. The included bubble-blocking robot has an automatic bubble-blocking function; the bubble-blocking robot shares the same guide rail with the punching and filling robot, and the coplanarity of the bubble-blocking angle and the punching and filling angle ensures accurate bubble-blocking. The included loading and unloading robot can automatically complete the loading and unloading tasks between the sheet material and the foaming mold frame. This invention's sheet foaming production line has a high degree of automation, reducing the labor intensity of workers and improving the overall production efficiency of the production line.

[0062] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0063] like Figure 1 and 2 As shown, a six-station roller-type foaming line for sheet materials includes:

[0064] Support frame 1, two support frame 1s are arranged vertically opposite to each other;

[0065] The roller frame 2 is horizontally mounted on the top of the two support frames 1. The roller frame 2 includes a horizontally arranged main shaft 21. The ends of the main shaft 21 are rotatably connected to the top of the corresponding support frame 1 through support shaft seats 211. A regular hexagonal turntable 22 is axially fixedly connected to the main shaft 21.

[0066] A drive gear 3 is axially fixed on the end face of one of the regular hexagonal turntables 22, and the drive gear 3 is used to drive the roller frame 2 to rotate circumferentially.

[0067] The foaming mold frame 4 is composed of an upper template 41 and a lower template 42 that are hinged together. The ends of the upper template 41 are respectively fixedly connected to the edges of the corresponding regular hexagonal turntable 22.

[0068] The mold-connecting device 5 is used to support the lower template 42 to realize mold opening and mold closing. The mold-connecting device 5 is horizontally arranged below one side of the roller frame 2.

[0069] The mold locking device 6 is used to lock and unlock the upper mold plate 41 and the lower mold plate 42; the opening and closing angle of the mold locking device 6 is when the foaming mold frame 4 is rotated to a 60° angle with the horizontal plane.

[0070] The punching and filling robot 7 is used to punch holes in the sheet 10 placed in the foaming mold frame 4 and fill it with foaming material; the punching and filling robot 7 is suspended above the mold receiving device 5;

[0071] The bubble-blocking robot 8 is used to pick up the bubble-blocking plug and block the filling hole punched by the drilling and filling robot 7 on the plate 10; the bubble-blocking robot 8 and the drilling and filling robot 7 share the same guide rail that is horizontally suspended on the outside of the top of the support frame 1, and the bubble-blocking angle, the drilling angle and the filling angle are all 50° with the horizontal plane.

[0072] The loading and unloading robot 9 is used to pick up and place the sheet metal 10 horizontally. The loading and unloading robot 9 is horizontally arranged outside the mold receiving device 5.

[0073] By adopting the above technical solution, the foaming line uses a horizontal axis vertical rotation structure, with two hexagonal turntables rotating around the main shaft, driven by a drive gear. Six foaming mold frames are installed between the two hexagonal turntables of the roller frame, forming six circulating foaming stations, saving production time and costs. The mold-connecting device and mold-locking device work together to efficiently complete the opening and closing operations of the foaming mold frames. The punching and filling robot completes punching and filling on the same robot, ensuring the coplanarity of the punching and filling angles. The bubble-blocking robot has an automatic bubble-blocking function; the bubble-blocking robot shares the same guide rail with the punching and filling robot, and the coplanarity of the bubble-blocking angle and the punching and filling angle ensures accurate bubble blocking. The loading and unloading robot can automatically complete the loading and unloading tasks between the sheet material and the foaming mold frame.

[0074] like Figure 2As shown, the outer end face of the drive gear 3 has six circumferentially spaced positioning holes 31; two positioning cylinders 11 are longitudinally offset on the support frame 1 on the same side as the drive gear 3. When the piston rod of the lower positioning cylinder 11 passes through the positioning hole 31 at the lowest point of the drive gear 3, the foaming mold frame 4 forms a 60° angle with the horizontal plane; when the piston rod of the upper positioning cylinder 11 passes through the positioning hole 31 rotated from the lowest point of the drive gear 3, the foaming mold frame 4 forms a 50° angle with the horizontal plane.

[0075] By adopting the above technical solution, the positioning hole 31 and the positioning cylinder 11 can better position the mold opening angle, as well as the drilling, filling, and blocking angles of the foaming mold frame, so as to prevent the roller frame from rotating unexpectedly.

[0076] like Figure 3 As shown, circulating water pipes are evenly distributed inside the upper template 41 and the lower template 42. The circulating water pipes are connected to the external mold temperature controller through a circulating water integrated frame 221 that is axially fixed to the end face of another hexagonal turntable 22.

[0077] The circulating water integrated frame 221 includes a regular hexagonal water pipe 2211. Two regular hexagonal water pipes 2211 are axially connected and superimposed through multiple circumferentially uniformly arranged connecting columns 2212. Two valves 2213 are arranged opposite each other at the same position on the edges of the two regular hexagonal water pipes 2211. The two valves 2213 on the same edge of one of the regular hexagonal water pipes are respectively connected to the circulating water pipe inlets in the upper template 41 and the lower template 42 through water pipes. The two valves 2213 at the same position on the other regular hexagonal water pipe 2211 are respectively connected to the circulating water pipe outlets in the upper template 41 and the lower template 42 through water pipes.

[0078] The end of the main shaft 21 is hollow. A rotary joint 2215 is axially arranged inward on the end face of the main shaft 21. The water inlet pipe and water outlet pipe of the external mold temperature controller are axially connected in parallel inside the rotary joint 2215. Water inlets 2214 are radially symmetrically arranged on the two regular hexagonal water pipes 2211. The two water inlets 2214 are respectively connected to the end of the corresponding main shaft 21 through water pipes.

[0079] By adopting the above technical solution, the foaming mold frame uses circulating water heating, and the temperature and water volume are controlled by a mold temperature controller. The foaming of the board is heated more evenly, and the power of the mold temperature controller is reasonably selected, with a temperature range of 20-60℃. The two hexagonal water pipes in the circulating water integrated frame are axially connected and stacked, and then fixed on the hexagonal turntable to rotate synchronously with it. The rotary joint is axially connected to the end of the hollow main shaft, so that the main shaft rotates but the rotary joint does not rotate with it. The hot water from the external mold temperature controller enters the end of the main shaft, and then a circulating water circuit is formed by two water inlets, two hexagonal water pipes, and multiple valves.

[0080] like Figure 1 , 2 As shown in Figure 7, the mold receiving device 5 includes a linkage shaft 51, and mold receiving arms 52 are axially symmetrically fixedly connected to the ends of the linkage shaft 51. The mold receiving arms 52 are rotatably supported and connected by the mold receiving drive mechanism 53.

[0081] The end face of the lower template 42 is vertically and symmetrically connected with rollers 421. A safety rod 4211 is horizontally arranged on one side of the rollers 421, and the outer diameter of the safety rod 4211 is smaller than the outer diameter of the rollers 421. When the mold receiving arm 52 rotates to the highest point of mold receiving, it contacts and supports the rollers 421 on the same side.

[0082] By adopting the above technical solution, the roller contact support between the mold connecting arm and the lower template can smoothly drive the lower template to rotate to the required position; the safety bar can provide temporary support in case the roller breaks; as can be seen from the attached figure, the mold connecting drive mechanism uses a geared motor to drive the gear to rotate via universal joints on both sides, and the gear synchronously drives the arc rack on the mold connecting arm to rotate.

[0083] like Figure 4 and 5 As shown, a fixed template 422 is detachably fixed at one end of the top surface of the lower template 42 along its short side; a fixed template segment 423 is detachably fixed at equal intervals along the long side of the outer side of the top surface of the lower template 42; a movable template 424 is slidably placed on the inner side of the top surface of the lower template 42 along its long side, and the movable template 424 is pushed by a template driving mechanism 425; a steel plate 426 is embedded at equal intervals parallel to the fixed template segment 423 on the top surface of the lower template 42, and the steel plate 426 is parallel to the fixed template segment 423, and the top surface of the steel plate 426 is flush with the top surface of the lower template 42; a magnetic template 427 is magnetically attracted to the steel plate 426, the magnetic template 427 is parallel to the fixed template 422, and the length of the magnetic template 427 is adapted to the width of the plate 10.

[0084] By adopting the above technical solution, the fixed mold strip, fixed mold segment, movable mold strip, and magnetic mold strip together form an adjustable board positioning mechanism, which can position and clamp boards of different sizes. This foaming production line can produce products of multiple specifications and has better versatility. The fixed mold segments that are spaced apart are for easy drilling, filling, and sealing of the board from the outside. The contact surfaces between the lower mold and the board are made of aluminum, so a steel plate needs to be embedded to magnetically attract the magnetic mold strip.

[0085] like Figure 6 As shown, the plate 10 has a hollow, stepped structure. The plate 10 is assembled from a lower plate 101 and an upper plate 102, and the size of the lower plate 101 is smaller than the size of the upper plate 102. The fixing strip 422, fixing segment 423, moving strip 424 and magnetic strip 427 are respectively tightly fitted to the side of the corresponding lower plate 101, and the bottom surface of the lower plate 101 is attached to the top surface of the lower template 42.

[0086] By adopting the above technical solutions, stepped structured plates are widely used in the lithium battery industry; the perforation position during foaming of such plates is located on the long side of the lower plate.

[0087] like Figure 4 and 5 As shown, the template drive mechanism 425 includes a scissor fork 4251. A first slide block 4252 is vertically connected to the bottom end of the pin of the scissor fork 4251. A first slide rail 4253 is horizontally slidably connected to the bottom of the first slide block 4252. A mounting groove 4254 is formed on one side of the top surface of the lower template 42 along its short side. The first slide rail 4253 is embedded in the mounting groove 4254. One side of the scissor fork 4251 is hinged to the end of the corresponding movable template 424, and the lower part of the other side of the scissor fork is hinged to... The second slide block 4255 has a second slide rail 4256 horizontally slidably connected to its bottom, and the second slide rail 4256 is fixedly connected along the long side of the corresponding lower template 42; a push plate 4257 is vertically suspended on one end face of the second slide block 4255, and a drive cylinder 4258 is horizontally opposite to the two push plates 4257. The drive cylinder 4258 is fixedly connected to the long side of the corresponding lower template 42, and the piston rod of the drive cylinder 4258 is vertically connected to the corresponding push plate 4257.

[0088] By adopting the above technical solution, the piston rods of the two drive cylinders retract synchronously, and the push plate drives the second slide block to move inward along the second slide rail. In this way, the scissor fork moves along the first slide rail through the first slide block, thereby pushing the moving mold strip to press against the plate. The entire mold strip drive mechanism has a reasonable structural design, and the scissor fork can apply force more smoothly.

[0089] like Figure 8 , 9 As shown in Figures 11 and 12, the locking device 6 includes a movable locking module 61. The movable locking module 61 is symmetrically arranged on the long side of the upper template 41. The movable locking module 61 includes a linkage straight plate 611. The linkage straight plate 611 is laterally limited and slidably connected to the corresponding long side of the upper template 41. Multiple suspension plates 612 are fixedly arranged at equal intervals on the outer surface of the linkage straight plate 611. A pin 613 is vertically connected to the bottom of the inner surface of the suspension plate 612. A roller 6131 is rotatably connected to the end of the pin 613.

[0090] The locking module 62 is provided with multiple locking modules 62 arranged at equal intervals on the long side of the lower template 42. Each locking module 62 includes a fixing plate 621, which is fixedly attached to the long side of the lower template 42. The outer surface of the fixing plate 621 is provided with a Z-shaped guide groove 622, and the width of the guide groove 622 is the same as the outer diameter of the roller 6131.

[0091] The opening and closing locking mechanism 63 is symmetrically arranged laterally on both short sides of the upper template 41. The opening and closing locking mechanism 63 includes a mounting plate 631, which is inclinedly connected to the corresponding support frame 1 at an angle of 60°. A reducer 632 is vertically installed in the middle of the outer surface of the mounting plate 631. A motor 633 is longitudinally connected to the power input end of the reducer 632. A rotating shaft 634 is symmetrically connected axially to the bidirectional power output end of the reducer 632. A retractable impact member 635 is vertically symmetrically arranged at the end of the rotating shaft 634. The impact member 635 is used to impact the end of the corresponding linkage straight plate 611.

[0092] By adopting the above technical solution, the locking device has symmetrically arranged movable locking modules on the long side of the upper mold plate and symmetrically arranged fixed locking modules on the long side of the lower mold plate. Opening and closing locking mechanisms are symmetrically arranged on the two short sides of the upper mold plate. The movable locking modules, fixed locking modules, and opening and closing locking modules work together to automatically lock and unlock the closed upper and lower mold plates. This facilitates rapid mold closing and opening of the board foaming mold frame, effectively improving the overall foaming efficiency of the board. The symmetrically arranged movable and fixed locking modules provide better double locking of the upper and lower mold plates, preventing damage to the hinge joints of the upper and lower mold plates after prolonged use. The rollers roll into the guide grooves of the corresponding Z-shaped structure from the higher opening, creating a height difference, which increases the locking force between the upper and lower mold plates.

[0093] like Figure 13 As shown, the impact member 635 includes a guide cylinder 6351, which is vertically and fixedly connected to the end of the mounting plate. An impact rod 6352 is laterally slidably inserted inside the guide cylinder 6351. A straight tooth section 63521 is laterally provided on the top surface of the end of the impact rod 6352 facing away from the mounting plate, and the top surface of the straight tooth section 63521 is in close contact with the inner top surface of the guide cylinder 6351. A transmission gear 6353 is meshed on the straight tooth section 63521 of the impact rod 6352. The transmission gear 6353 is axially connected to the end of the shaft corresponding to the rotating shaft. A bearing seat 6354 is axially sleeved on the rotating shaft, and the bearing seat 6354 is vertically connected to the end of the mounting plate corresponding to the rotating plate.

[0094] By adopting the above technical solution, the rotating shaft drives the transmission gear to rotate synchronously through the bearing seat. The transmission gear meshes and drives the spur section to move, thereby synchronously driving the impact rod to move along the guide cylinder to push the linkage plate to move laterally. The impact component design of this gear transmission method makes it easy to push the roller on the linkage plate to engage or disengage into place.

[0095] like Figure 3 As shown, the linkage straight plate 611 has multiple guide holes 6111 that are horizontally and equally spaced through it, and the suspension plate 612 is correspondingly arranged in the middle between two adjacent guide holes 6111; the long side of the foaming mold frame 4 of the board 10 is fixedly provided with mounting blocks 614 with L-shaped cross-sections at horizontally and equally spaced, and the vertical part of the mounting block 614 is vertically connected to a T-shaped limiting block 615. The vertical part of the limiting block 615 is horizontally slidably sleeved with the corresponding guide hole 6111, and the top surface of the horizontal part of the mounting block 614 is horizontally slidably attached to the bottom surface of the linkage straight plate 611; when the roller 6131 rolls into or out of the guide groove 622, the vertical part of the limiting block 615 abuts against the end of the corresponding guide hole 6111.

[0096] By adopting the above technical solution, the guide straight hole, the mounting block and the limiting block are designed to work together to allow the linkage straight plate to be laterally limited and slidably connected to the long side of the upper template. When the roller rolls into or out of the guide groove, the vertical part of the limiting block abuts against the end of the corresponding guide straight hole, which makes it easy to determine whether the roller has entered or exited the guide groove.

[0097] The usage method of a six-station roller-type foaming line for sheet materials includes the following steps:

[0098] Step S1: The sheet metal 10 is positioned and stacked on one side of the loading / unloading robot 9;

[0099] Step S2: First, the foaming mold frame 4 is rotated to an opening angle of 60° with the horizontal plane. The mold receiving arm 52 is rotated to the highest point of mold receiving and is in contact with the roller 421 on the end face of the lower mold plate 42. Then, the impact member 635 of one of the opening and closing locking mechanisms 63 impacts the end of the corresponding linkage straight plate 611 to unlock the foaming mold frame 4. At the same time, the mold receiving arm 52 drives the lower mold plate 42 to rotate downward to a horizontal position.

[0100] Step S3: First, the loading and unloading robot 9 picks up the positioned sheet 10 and moves horizontally to above the positioning edge formed by the fixed mold strip 422 and the fixed mold segment 423 on the top surface of the foaming mold frame 4. Then, the loading and unloading robot 9 lowers the sheet 10 and returns to its original position.

[0101] Step S4: First, the moving mold strip 424 moves toward the fixed mold section 423 under the action of the driving cylinder 4258 to position and press against the plate 10. Then, the magnetic mold strip 427 is manually used to position the plate 10.

[0102] Step S5: First, the mold receiving arm 52 rotates upward to the mold closing position, and the impact member 635 of the other opening and closing locking mechanism 63 impacts the end of the corresponding linkage straight plate 611 to lock the foaming mold frame 4. Then, the mold receiving arm 52 rotates down to return to its original position.

[0103] Step S6: First, the foaming mold frame 4 rotates 10° in the same direction to a position 50° with the horizontal plane for drilling, filling, and plugging the board 10. Then, the drilling and filling robot 7 moves horizontally to the pre-reserved opening position on the product and starts its own drilling drill to perform drilling operations. After the filling hole is opened, it starts its own filling gun head to fill the foaming material. After filling is completed, the drilling and filling robot 7 moves laterally to the end of the guide rail. During the drilling and filling process, the bubble plugging robot 8 picks up the bubble plug and waits beside it. After filling is completed, it immediately moves to the filling hole to plug the bubble.

[0104] Step S7: First, the foaming mold frame 4 that has completed the above steps is rotated 50° in the same direction to a horizontal state. The board 10 inside the foaming mold frame 4 enters the foaming and curing time. At this time, the next foaming mold frame 4 is exactly at a 60° opening angle with the horizontal plane. Then, the mold receiving arm 52 rotates to the highest point of mold receiving, and the impact member 635 of the opening and closing locking mechanism 63 impacts and unlocks the foaming mold frame 4. At the same time, the mold receiving arm 52 drives the lower template 42 to rotate downward to a horizontal position.

[0105] Step S8: First, the moving mold strip 424 returns to its original position under the action of the drive cylinder 4258. At the same time, the magnetic mold strip 427 is manually removed. Then, the loading and unloading robot 9 moves horizontally to the position of the lower mold 42, descends and picks up the foamed board 10, and then moves horizontally to place the foamed board 10 onto the unloading conveyor line. The foaming of the board 10 is completed.

[0106] By adopting the above technical solution, the method of use is consistent and can load boards sequentially or intermittently, making it flexible and adaptable to foaming boards of various specifications.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
