Description

Technical Field

[0001] This invention relates to the field of automated production equipment, and in particular to a system and method for applying protective stickers around fireproof composite panels. Background Technology

[0002] Fire-resistant composite panels are a new type of non-combustible decorative material made from a ternary system of magnesium oxide, magnesium chloride, and water, formulated with modifiers. This system utilizes a stable magnesium-based cementitious material, reinforced with medium-alkaline fiberglass mesh, and filled with lightweight materials. After roll forming, drying, and edge trimming, the fire-resistant composite panels are stacked and bundled before storage and sale. To prevent damage to the edges during stacking, bundling, and transportation, protective stickers are applied to the outer edges of the panels. This involves first applying single-sided adhesive protective stickers to the outer edges of the panels, then smoothing out any excess stickers beyond the top and bottom surfaces and sticking them to the top and bottom surfaces of the panel. This method results in high labor intensity and low efficiency for workers. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective sticker application system and method for fire-resistant composite panels, thereby improving the efficiency of protective sticker application.

[0004] The technical solution of the present invention is as follows: a protective sticker application system for fireproof composite panels, comprising a front and rear protective sticker application machine, a left and right protective sticker application machine, and a composite panel conveying device. The composite panel conveying device sequentially transports the fireproof composite panel to the front and rear protective sticker application machines and the left and right protective sticker application machines to apply the protective sticker.

[0005] The front and rear protective sticker applicator and the left and right protective sticker applicator both include a protective sticker applicator and a fixing component. The protective sticker applicator includes a main support, a tissue box assembly, a mounting plate, a guide rod, a first double-rod cylinder, a telescopic spring, a protective sticker fixing frame, a protective sticker, and a double-rod cylinder. The guide rod is mounted on the main support, and the two sets of tissue boxes are movably mounted on the guide rod. The two mounting plates are fixedly mounted on the main support, and several horizontally arranged first double-rod cylinders are mounted on the two mounting plates respectively. The piston rod ends of the first double-rod cylinders mounted on the two mounting plates are respectively fixedly connected to the two sets of tissue boxes, driving the two sets of tissue boxes to move relative to or away from each other.

[0006] The protective sticker holder is fitted with a cylindrical protective sticker. The protective sticker holder is slidably connected to the main support. A horizontally arranged telescopic spring is provided between the protective sticker holder and the main support. The double-rod cylinder is horizontally fixed on the main support. The telescopic end of the double-rod cylinder abuts against the side of the protective sticker.

[0007] The tissue box assembly includes an L-shaped mounting plate, a linear motion drive mechanism, a second telescopic mechanism, a clamping gripper, a clamping strip, a shearing blade, a shearing gripper, and a third telescopic mechanism. The linear motion drive mechanism is horizontally mounted on the L-shaped mounting plate. The second and third telescopic mechanisms are mounted parallel to each other on the linear motion drive mechanism. A shearing gripper is mounted on the telescopic end of the third telescopic mechanism, and a shearing blade is mounted on the gripper. A clamping gripper is mounted on the telescopic end of the second telescopic mechanism, and a clamping strip is mounted on the gripper. The shearing blade is used to cut the protective sticker, and the clamping strip is used to hold the protective sticker.

[0008] The protective sticker application components of the front and rear protective sticker application machines and the left and right protective sticker application machines are arranged with a relative horizontal rotation of 90°.

[0009] The fixing components are arranged in pairs on both sides of the conveying direction of the composite board conveying equipment. The fixing components include a third bracket, a transverse mounting plate, vacuum suction cups and a fourth telescopic mechanism. The fourth telescopic mechanism is installed on the crossbeam of the third bracket. The telescopic end of the fourth telescopic mechanism is fixedly connected to the transverse mounting plate. Several vacuum suction cups are installed on the top surface of the transverse mounting plate.

[0010] Furthermore, the linear motion drive mechanism is a linear motion drive mechanism based on screw and nut transmission, a linear motion drive mechanism based on gear and rack transmission, a linear motion drive mechanism based on belt transmission, or a linear motion drive mechanism based on chain transmission.

[0011] Furthermore, the composite plate conveying equipment is an AGV (Automated Guided Vehicle).

[0012] Furthermore, both the front and rear protective sticker applicator and the left and right protective sticker applicator include an adjustment component. The adjustment components are arranged in pairs on both sides of the conveying direction of the composite board conveying equipment. The adjustment component includes a second bracket, a strip adjustment plate, and a second telescopic cylinder. The second telescopic cylinder is horizontally installed on the crossbeam of the second bracket, and the end of the piston rod of the second telescopic cylinder is fixedly connected to one side of the strip adjustment plate.

[0013] Furthermore, the attitude adjustment component is located outside the fixing component.

[0014] Furthermore, both the front and rear protective sticker applicator and the left and right protective sticker applicator include a limiting component. The posture adjustment component is located on the side of the fixing component. The limiting component includes a fourth bracket, a sixth telescopic mechanism, and an L-shaped baffle. The sixth telescopic mechanism is vertically installed on the crossbeam of the fourth bracket, and the L-shaped baffle is installed at the telescopic end of the sixth telescopic mechanism.

[0015] Furthermore, the protective sticker applicator on the left and right sides includes a lifting assembly. The lifting assemblies are arranged in pairs on both sides of the conveying direction of the composite board conveying equipment. The lifting assembly includes a No. 8 bracket, a lifting plate, and a No. 7 telescopic mechanism. The No. 7 telescopic mechanism is vertically installed on the crossbeam of the No. 8 bracket, and the telescopic end of the No. 7 telescopic mechanism is fixedly connected to the lifting plate.

[0016] Furthermore, the lifting component is located inside the fixing component.

[0017] Furthermore, the second, third, fourth, sixth, and seventh telescopic mechanisms are telescopic cylinders or electric cylinders.

[0018] Another technical solution of the present invention is: a method for applying protective stickers around the perimeter of a fire-resistant composite board, the method being based on the aforementioned protective sticker application system for fire-resistant composite boards, and comprising the following steps:

[0019] 1) The fireproof composite board conveying equipment transports the fireproof composite board to the protective sticker application machines on both the front and rear sides;

[0020] 2) The front and rear protective sticker applicator positions and fixes the fireproof composite board and applies protective stickers to the outer edges of the front and rear sides. The specific process is as follows:

[0021] 2.1) The piston rod of the second telescopic cylinder of the posture adjustment component extends, driving the strip posture adjustment plate to move closer to the fireproof composite plate, thereby adjusting the posture of the fireproof composite plate.

[0022] 2.2) The telescopic end of the fourth telescopic mechanism of the fixed component extends, driving the horizontal mounting plate and the vacuum suction cup installed on it to move upward. The vacuum suction cup is activated to adsorb the fireproof composite board, ensuring that the position of the fireproof composite board remains unchanged.

[0023] 2.3) The piston rod of the second telescopic cylinder of the attitude adjustment component retracts, causing the strip attitude adjustment plate to move away from the fireproof composite board.

[0024] 2.4) The telescopic end of the second telescopic mechanism of the tissue box assembly extends, driving the clamping air claw to move down. The two air claws of the clamping air claw of the tissue box assembly close, and the clamping strip clamps the starting end of the cylindrical protective sticker.

[0025] 2.5) The linear motion drive mechanism of the tissue box assembly drives the second and third telescopic mechanisms to move along one side of the fireproof composite board to pull out the protective sticker.

[0026] 2.6) The piston rod of the No. 1 double-rod cylinder retracts, and at the same time the piston rod of the double-rod cylinder extends. The protective sticker pulled out from the cylindrical protective sticker gradually moves towards the outer edge of the fireproof composite board until the protective sticker is applied to the outer edge of the fireproof composite board.

[0027] 2.7) The telescopic end of the second telescopic mechanism of the tissue box assembly retracts, causing the clamping gripper and its clamping bar to move upward.

[0028] 2.8) The linear motion drive mechanism of the tissue box assembly drives the clamping gripper and the shearing gripper to move in the opposite direction along one side of the fireproof composite board until the shearing blade installed on the gripper reaches the longitudinal left edge of the fireproof composite board. The telescopic end of the No. 3 telescopic mechanism extends, driving the shearing gripper to move down. The closing of the shearing gripper drives the shearing blade to close, cutting off the protective sticker that extends out of the left edge of the fireproof composite board.

[0029] 2.9) The telescopic end of the third telescopic mechanism of the tissue box assembly retracts, causing the shearing gripper and the shearing blade mounted on it to move upward.

[0030] 2.10) The linear motion drive mechanism of the tissue box assembly drives the clamping gripper and the shearing gripper to move in the opposite direction along one side of the fireproof composite board until the shearing blade installed on the gripper of the shearing gripper reaches the right longitudinal edge of the fireproof composite board.

[0031] 2.11) The telescopic end of the second telescopic mechanism extends, causing the clamping gripper and its clamping bar to move downward, the clamping gripper closes, and the clamping bar clamps the protective sticker.

[0032] 2.12) The telescopic end of the No. 3 telescopic mechanism extends, driving the shearing gripper and the shearing blade installed on it to move down. The shearing blade closes, cutting off the protective sticker on the right edge of the fireproof composite board.

[0033] 2.13) The piston rod of the No. 1 double-rod cylinder extends, pushing the paper-drawing assembly to move in the direction away from the longitudinal center line of the base plate, while the piston rod of the double-rod cylinder retracts.

[0034] 2.14) The vacuum suction cup is inflated to release the adsorption on the fireproof composite board. The telescopic end of the fourth telescopic mechanism of the fixed component arranged on the bottom plate of the main support retracts, driving the horizontal mounting plate and the vacuum suction cup (34) installed on it to move down.

[0035] 3) The composite board conveying equipment transports the fireproof composite board to the protective sticker application machines on the left and right sides;

[0036] 4) The protective sticker applicator on both sides lifts, positions, and fixes the fireproof composite board, and applies protective stickers to the outer edges of both sides. The specific process is as follows:

[0037] 4.1) The telescopic end of the No. 7 telescopic mechanism extends, causing the lifting plate to move upward relative to the crossbeam of the No. 8 bracket, thus lifting the fireproof composite panel.

[0038] 4.2) Similar to the process of positioning, fixing and applying protective stickers to the fireproof composite board by the front and rear protective sticker applicator, the process of applying protective stickers to the outer edges of the front and rear sides by the left and right protective sticker applicator is the same as that of positioning, fixing and applying protective stickers to the outer edges of the left and right sides of the fireproof composite board by the left and right protective sticker applicator.

[0039] 4.3) The telescopic end of the No. 7 telescopic mechanism retracts, causing the lifting plate to move down relative to the crossbeam of the No. 8 bracket, thus lowering the fireproof composite panel and placing it on the composite panel conveying equipment.

[0040] 5) The composite panel conveying equipment moves the fireproof composite panel to the next work station.

[0041] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0042] 1) Protective stickers are applied simultaneously on the outer edges of both longitudinal and transverse sides of the fireproof composite board, which improves work efficiency.

[0043] 2) By using a telescopic spring and a double-rod cylinder, the position of the protective sticker fixing bracket is adaptively adjusted according to the cylindrical diameter of the remaining protective sticker, thereby ensuring that the fireproof composite board is reliably applied to the outer edges of the fireproof composite board.

[0044] 3) After the fireproof composite panel is positioned, the lower surface of the fireproof composite panel is adsorbed by a vacuum suction cup to fix the fireproof composite panel after the position adjustment. This avoids the traditional fixing method of pressing the upper surface of the fireproof composite panel and solves the problem of easy interference.

[0045] 4) The posture adjustment component drives the fireproof composite panel to adjust its position through a telescopic cylinder, making full use of the compressibility of compressed air to adapt to the dimensional changes of the fireproof composite panel caused by errors, and ensuring the accurate positioning of the fireproof composite panel.

[0046] 5) The entire process of adjusting the position and fixing the fireproof composite board, as well as applying protective stickers to the outer edges, is automated, which improves the efficiency of applying protective stickers.

[0047] 6) After the protective sticker is pulled out, the paper-pulling assembly is driven by the cylinder to gradually move towards the outer edge of the fireproof composite board, thereby applying the protective sticker to the outer edge of the fireproof composite board. This fully utilizes the compressibility of compressed air to adapt to the dimensional changes of the fireproof composite board caused by errors, ensuring reliable application of the protective sticker to the outer edges of the fireproof composite board.

[0065] The present invention will be further described below with reference to embodiments, but these are not intended to limit the scope of the invention.

[0066] like Figure 1 As shown, the fireproof composite board protective sticker application system is used in the fireproof composite board protective sticker application production line. It includes front and rear protective sticker application machines A, left and right protective sticker application machines B, and composite board conveying equipment C, wherein the composite board conveying equipment C is an AGV trolley.

[0067] AGV C transports the fireproof composite panel to the front and rear protective sticker applicator A. Protective sticker applicator A applies protective stickers to the outer edges of the front and rear sides of the fireproof composite panel. Then, AGV C moves the fireproof composite panel to the left and right protective sticker applicator B. Left and right protective sticker applicator B applies protective stickers to the outer edges of the left and right sides of the fireproof composite panel. The AGV then transports the fireproof composite panel to the next workstation. Both front and rear protective sticker applicator A and left and right protective sticker applicator B have protective sticker applicator components, posture adjustment components, fixing components, and limiting components. The components of front and rear protective sticker applicator A are designated as No. 1, and the components of left and right protective sticker applicator B are designated as No. 2.

[0068] like Figure 2 and Figure 3 As shown, the front and rear protective sticker applicator A includes a first protective sticker applicator 1, a first posture adjustment component 2, a first fixing component 3, and a first limiting component 4. The two first posture adjustment components 2 are symmetrically arranged on both sides of the base plate 11.1 of the main support 11 with the longitudinal center line of the base plate 11.1 as the axis of symmetry. The first fixing component 3 is symmetrically arranged on both sides of the base plate 11.1 of the main support 11 with the longitudinal center line of the base plate 11.1 as the axis of symmetry and is located inside the two first posture adjustment components 2. The two first limiting components 4 are arranged symmetrically on the right end of the base plate 11.1 of the main support 11 with the longitudinal center line of the base plate 11.1 as the axis of symmetry.

[0069] like Figures 4 to 10As shown, the first protective sticker application component 1 includes a main support 11, a tissue box assembly 12, a mounting plate 13, guide rods 14, a first double-rod cylinder 15, a telescopic spring 16, a protective sticker holder 17, a protective sticker 18, and a double-rod cylinder 19. Two guide rods 14 are mounted parallel to each other between the front rod 11.4 and the rear rod 11.2 of the main support 11 via T-shaped smooth rod mounting seats. Two tissue box assemblies 12 are movably mounted on the two guide rods 14, respectively, back-to-back, via linear bearings. Two mounting plates 13 are fixedly mounted parallel to each other between the left rod 11.3 and the right rod 11.8 of the main support 11, and are located inside the two tissue box assemblies 12. Two No. 1 double-rod cylinders 15 are respectively installed on the upper surfaces of the two mounting plates 13. The piston rod ends of the No. 1 double-rod cylinders 15 installed on the upper surfaces of the two mounting plates 13 are respectively fixedly connected to the two sets of paper-drawing assemblies 12. When the piston rods of the No. 1 double-rod cylinders 15 installed on the upper surfaces of the two mounting plates 13 extend or retract, they respectively drive the two sets of paper-drawing assemblies 12 to move along the two guide rods 14. The protective sticker holder 17 is an assembly consisting of a top plate 17.2, a horizontal guide rod 17.3, and a vertical cylindrical rod 17.1. A cylindrical protective sticker 18 is fitted onto the vertical cylindrical rod 17.1 of the protective sticker holder 17. The top plates 17.2 of the two protective sticker holders 17 are respectively inserted into the front moving slot 11.5 and the rear moving slot 11.10 of the main bracket 11. The horizontal guide rods 17.3 are respectively inserted into the front guide hole 11.7 and the rear guide hole 11.9. Two telescopic springs 16 are respectively fitted into the horizontal guide rods 17.3 of the two protective sticker holders 17. Under the action of the spring force of the telescopic springs 16, the two protective sticker holders 17 are pushed outward in the front moving slot 11.50 and the rear moving slot 11.1 of the main bracket 11. Two No. 1 double-rod cylinders 15 are respectively mounted on the front support plate 11.6 and the rear support plate 11.11 of the main bracket 11, and the ends of their piston rods are perpendicular to the vertical cylindrical rods 17.1 of the two protective paper fixing brackets 17.

[0070] like Figure 11As shown, the tissue box assembly 12 includes an L-shaped mounting plate 1201, a first motor 1202, a first linear bearing 1203, a first drive plate 1204, a clamping cylinder 1205 (second telescopic mechanism), a first guide rod 1206, a first lead screw 1207, a first bearing with a seat 1208, a first T-shaped light rod mounting base 1209, a clamping gripper 1210, a clamping bar 1211, a shearing blade 1212, a shearing gripper 1213, and a shearing cylinder 1214 (third telescopic mechanism). The first lead screw 1207 is mounted in the middle of the vertical plane of the L-shaped mounting plate 1201 via the first bearing 1208. A bevel gear is mounted at one end of the first lead screw 1207. Two first guide rods 1206 are parallel to each other and symmetrically positioned on both sides of the vertical plane of the L-shaped mounting plate 1201 via the first T-shaped smooth rod mounting seat 1209. The first drive plate 1204 is mounted on the two first guide rods 1206 via the first linear bearing 1203, and is aligned with the first... The lead screw 1207 is fixedly connected to the nut (not shown in the figure). The shearing cylinder 1214 and the clamping cylinder 1205 are mounted parallel to each other on the first drive plate 1204. The piston rod end of the shearing cylinder 1214 is equipped with a shearing gripper 1213, and the gripper of the shearing gripper 1213 is equipped with a shearing blade 1212. The piston rod end of the clamping cylinder 1205 is equipped with a clamping gripper 1210, and the gripper of the clamping gripper 1210 is equipped with a clamping bar 1211. The first motor 1202 is mounted on the back of one end of the vertical surface of the L-shaped mounting plate 1201. Its output shaft is equipped with a bevel gear. The bevel gear mounted on one end of the lead screw 1207 meshes with the bevel gear mounted on the output shaft of the first motor 1202.

[0071] like Figure 12 As shown, the first attitude adjustment component 2 includes a second bracket 21, a strip attitude adjustment plate 22, a second guide rod with a flange 23, a second linear bearing with a flange 24, and a second telescopic cylinder 25. The second support 21 consists of a crossbeam and two vertical rods. Two flanged linear bearings 24 are mounted on the crossbeam of the second support 21. Two flanged guide rods 23 pass through the two flanged linear bearings 24 respectively, and the flange ends of the two flanged guide rods 23 are fixedly connected to one side of the strip-shaped attitude adjustment plate 22, thereby movably mounting the strip-shaped attitude adjustment plate 22 on the crossbeam of the second support 21. The second telescopic cylinder 25 is mounted on the crossbeam of the second support 21. The piston rod of the second telescopic cylinder 25 passes through the through hole at the center of the crossbeam of the second support 21, and its end is fixedly connected to one surface of the strip-shaped attitude adjustment plate 22. When the piston rod of the second telescopic cylinder 25 extends or retracts, it drives the strip-shaped attitude adjustment plate 22 to move relative to the crossbeam of the second support 21.

[0072] like Figure 13As shown, the first fixing component 3 includes a third bracket 31, a third flanged linear bearing 32, a transverse mounting plate 33, vacuum suction cups 34, a third dual-axis cylinder 35 (a fourth telescopic mechanism), and a third flanged guide rod 36. The third bracket 31 consists of a crossbeam and two vertical rods. Two third flanged linear bearings 32 are mounted on the crossbeam. Two third flanged guide rods 36 pass through the two third flanged linear bearings 32 respectively, and the flange ends of the two third flanged guide rods 36 are fixedly connected to the lower surface of the transverse mounting plate 33, thereby allowing the transverse mounting plate 33 to be mounted vertically on the crossbeam of the bracket 31. The third dual-axis cylinder 35 is mounted on the crossbeam of the third bracket 31, and the piston rod end of the third dual-axis cylinder 35 is fixedly connected to the lower surface of the transverse mounting plate 33. Several vacuum suction cups 34 are mounted on the transverse mounting plate 33. When the piston rod of the third dual-axis cylinder 35 extends or retracts, it drives the transverse mounting plate 33 and the vacuum suction cup 34 mounted on it to move up and down relative to the crossbeam of the third bracket 31.

[0073] like Figure 14 As shown, the first limiting component 4 includes a fourth bracket 41, a fourth dual-axis cylinder 42 (a sixth telescopic mechanism), and an L-shaped baffle 43. The fourth bracket 41 has a door frame structure. The fourth dual-axis cylinder 42 is mounted on the crossbeam of the fourth bracket 41. The L-shaped baffle 43 is mounted on the end of the piston rod of the fourth dual-axis cylinder 42. When the piston rod of the fourth dual-axis cylinder 42 extends or retracts, it drives the L-shaped baffle 43 to move up and down relative to the crossbeam of the fourth bracket 41.

[0074] The working process of the front and rear protective sticker applicator A is as follows:

[0075] 1) The AGV trolley moves carrying the fireproof composite panel. The piston rod of the No. 4 dual-shaft cylinder 42 extends, causing the L-shaped baffle 43 to move upward, preventing the fireproof composite panel from moving forward. The AGV trolley stops moving.

[0076] 2) The piston rods of the second telescopic cylinders 25 of the two first posture adjustment components 2 arranged on the longitudinal sides of the base plate 11.1 of the main support 11 extend, driving the strip posture adjustment plate 22 to move closer to the fireproof composite plate, thereby adjusting the position and posture of the fireproof composite plate so that the longitudinal center line of the fireproof composite plate coincides with the longitudinal center line of the base plate 11.11 of the main support 11.

[0077] 3) The piston rod of the third dual-axis cylinder 35 of the first fixing component 3 arranged on the base plate 11.1 of the main support 11 extends, driving the horizontal mounting plate 33 and the vacuum suction cup 34 installed on it to move upward. The vacuum suction cup 34 is activated, firmly adsorbing the fireproof composite board and ensuring that the position of the fireproof composite board remains unchanged.

[0078] 4) The piston rods of the second telescopic cylinders 25 of the two first attitude adjustment components 2 arranged on the longitudinal sides of the base plate 11.1 of the main support 11 retract, driving the strip attitude adjustment plate 22 to move away from the fireproof composite board.

[0079] 5) The piston rod of the clamping cylinder 1205 of the tissue box assembly 12 extends, driving the clamping claw 1210 to move down. The two claws of the clamping claw 1210 of the tissue box assembly 12 close, and the clamping bar 1211 clamps the starting end of the cylindrical protective sticker 18.

[0080] 6) The first motor 1202 of the tissue box assembly 12 rotates, and through the bevel gear mechanism and the lead screw and nut mechanism, drives the clamping claw 1210 and the shearing claw 1213 to move along one side of the fireproof composite board, and pull out the protective sticker 18.

[0081] 7) The piston rod of the first double-rod cylinder 15 retracts, and at the same time the piston rod of the double-rod cylinder 19 extends. The protective sticker 18, which is pulled out from the cylindrical protective sticker, gradually moves towards the outer edge of the fireproof composite board until the protective sticker 18 is applied to the outer edge of the fireproof composite board.

[0082] 8) The piston rod of the clamping cylinder 1205 of the tissue box assembly 12 retracts, causing the clamping gripper 1210 and its clamping bar 1211 to move upward;

[0083] 9) The first motor 1202 of the tissue box assembly 12 rotates in the reverse direction, driving the clamping gripper 1210 and the shearing gripper 1213 to move in the opposite direction along one side of the fireproof composite board through the bevel gear mechanism and the lead screw and nut mechanism, until the shearing blade 1212 installed on the gripper of the shearing gripper 1213 reaches the longitudinal left edge of the fireproof composite board. The piston rod of the shearing cylinder 1203 extends, driving the shearing gripper 1213 to move down. The closing of the shearing gripper 1213 drives the shearing blade 1212 to close, cutting off the protective sticker 18 that extends out of the left edge of the fireproof composite board.

[0084] 10) The piston rod of the shearing cylinder 1214 of the paper dispenser assembly 12 retracts, causing the shearing gripper 1213 and the shearing blade 1212 mounted thereon to move upward.

[0085] 11) The first motor 1202 of the paper-pulling assembly 12 continues to rotate in the opposite direction, driving the clamping gripper 1210 and the shearing gripper 1213 to move in the opposite direction along one side of the fireproof composite board through the bevel gear mechanism and the lead screw and nut mechanism, until the shearing blade 1212 installed on the gripper of the shearing gripper 1213 reaches the right longitudinal edge of the fireproof composite board.

[0086] 12) The piston rod of the clamping cylinder 1205 extends, causing the clamping gripper 1210 and its clamping bar 1211 to move down. The clamping gripper 1210 closes, and the clamping bar 1211 clamps the protective sticker 18.

[0087] 13) The piston rod of the shearing cylinder 1214 extends, driving the shearing claw 1213 and the shearing blade 1212 mounted thereon to move down. The shearing blade closes, cutting off the protective sticker 18 on the right edge of the fireproof composite board.

[0088] 14) The piston rod of the first double-rod cylinder 15 extends, pushing the paper-drawing assembly 12 to move away from the longitudinal center line of the base plate 11.1, while the piston rod of the double-rod cylinder 19 retracts.

[0089] 15) The vacuum suction cup 34 is inflated, releasing the adsorption on the fireproof composite board. The piston rod of the first fixing component 3 and the third dual-axis cylinder 35 arranged on the base plate 11.1 of the main support 11 retracts, driving the horizontal mounting plate 33 and the vacuum suction cup 34 installed on it to move down.

[0090] 16) The AGV trolley carrying the fireproof composite board moves to the protective sticker applicator B on the left and right sides.

[0091] like Figure 15 and Figure 16 As shown, the protective sticker applicator B on both sides includes a second protective sticker applicator 5, a second posture adjustment component 6, a second fixing component 7, a lifting component 8, and a second limiting component 9. The two second posture adjustment components 8 are symmetrically arranged on both sides of the longitudinal axis of the rear main support base plate, with the longitudinal center line of the rear main support base plate as the axis of symmetry. The second fixing component 7 is symmetrically arranged on both sides of the longitudinal axis of the rear main support base plate, with the longitudinal center line of the rear main support base plate as the axis of symmetry, and is located inside the two second posture adjustment components 6. The two lifting components 8 are symmetrically arranged on both sides of the longitudinal axis of the rear main support base plate, with the longitudinal center line of the rear main support base plate as the axis of symmetry, and are located inside the two second fixing components 7. The two second limiting components 4 are arranged at the right end of the rear main support base plate, with the longitudinal center line of the rear main support base plate as the axis of symmetry. The second protective sticker application component 5 is structurally similar to the first protective sticker application component 1, except that the second protective sticker application component 5 is rotated 90 degrees relative to the first protective sticker application component 1 in terms of layout. The second posture adjustment component 6, the second fixing component 7, and the second limiting component 9 are the same as the first posture adjustment component 2, the first fixing component 3, and the first limiting component 4, respectively.

[0092] like Figure 17As shown, the lifting assembly 8 includes a bracket 81, a flanged linear bearing 82, a flanged guide rod 83, a lifting plate 84, and a dual-axis cylinder 85 (telescopic mechanism 7). The bracket 81 consists of a crossbeam and two vertical rods. Two flanged linear bearings 82 are mounted on the crossbeam of the bracket 81. Two flanged guide rods 83 pass through the two flanged linear bearings 82 respectively, and the flange ends of the two flanged guide rods 83 are fixedly connected to the lower surface of the lifting plate 84, thereby allowing the lifting plate 84 to be mounted vertically on the crossbeam of the bracket 81. The dual-axis cylinder 85 is mounted on the crossbeam of the bracket 81. The piston rod end of the dual-axis cylinder 85 is fixedly connected to the lower surface of the lifting plate 84. When the piston rod of the dual-axis cylinder 85 extends or retracts, it drives the lifting plate 84 to move vertically relative to the crossbeam of the bracket 81.

[0093] The working process of the protective sticker applicator B on the left and right sides is similar to that of the protective sticker applicator A on the front and rear sides. The difference is that during the working process of the protective sticker applicator B on the left and right sides, at the beginning, the lifting component 8 lifts up the fireproof composite board, and after the end, the fireproof composite board is lowered.

10. A method for applying protective stickers around the perimeter of a fireproof composite board, characterized in that, The application method is based on the fireproof composite board perimeter protective sticker application system of claim 7, and includes the following steps: 1) The fireproof composite board conveying equipment transports the fireproof composite board to the front and rear protective sticker applicator (A); 2) The front and rear protective sticker applicator (A) positions and fixes the fireproof composite board and applies protective stickers to the outer edges of the front and rear sides. The specific process is as follows: 2.1) The piston rod of the second telescopic cylinder (25) of the posture adjustment component extends, driving the strip posture adjustment plate (22) to move closer to the fireproof composite plate, thereby adjusting the posture of the fireproof composite plate. 2.2) The telescopic end of the fourth telescopic mechanism of the fixed component (3) extends out, driving the horizontal mounting plate (33) and the vacuum suction cup (34) installed on it to move upward. The vacuum suction cup (34) starts to adsorb the fireproof composite board, ensuring that the position of the fireproof composite board remains unchanged. 2.3) The piston rod of the second telescopic cylinder (25) of the posture adjustment component (2) retracts, causing the strip posture adjustment plate (22) to move away from the fireproof composite plate; 2.4) The telescopic end of the second telescopic mechanism of the tissue box assembly (12) extends out, driving the clamping air claw (1210) to move down. The two air claws of the clamping air claw (1210) of the tissue box assembly (12) close, and the clamping bar (1211) clamps the starting end of the cylindrical protective sticker (18). 2.5) The linear motion drive mechanism of the tissue box assembly (12) drives the second telescopic mechanism and the third telescopic mechanism to move along one side of the fireproof composite board and pull out the protective sticker (18); 2.6) The piston rod of the first double-rod cylinder (15) retracts, and at the same time the piston rod of the double-rod cylinder (19) extends. The protective sticker (18) pulled out from the cylindrical protective sticker gradually moves to the outer edge of the fireproof composite board until the protective sticker (18) is applied to the outer edge of the fireproof composite board. 2.7) The telescopic end of the second telescopic mechanism of the tissue box assembly (12) retracts, causing the clamping gripper (1210) and its clamping bar (1211) to move upward; 2.8) The linear motion drive mechanism of the tissue box assembly (12) drives the clamping gripper (1210) and the shearing gripper (1213) to move in the opposite direction along one side of the fireproof composite board until the shearing blade (1212) installed on the gripper of the shearing gripper (1213) reaches the longitudinal left edge of the fireproof composite board. The extension end of the telescopic mechanism No. 3 extends out, driving the shearing gripper (1213) to move down. The closing of the shearing gripper (1213) drives the shearing blade (1212) to close, cutting off the protective sticker (18) that extends out of the left edge of the fireproof composite board. 2.9) The telescopic end of the third telescopic mechanism of the tissue box assembly (12) retracts, causing the shearing gripper (1213) and the shearing blade (1212) mounted thereon to move upward; 2.10) The linear motion drive mechanism of the paper dispenser assembly (12) drives the clamping gripper (1210) and the shearing gripper (1213) to move in the opposite direction along one side of the fireproof composite board until the shearing blade (1212) installed on the gripper of the shearing gripper (1213) reaches the right longitudinal edge of the fireproof composite board. 2.11) The telescopic end of the second telescopic mechanism extends, causing the clamping air claw (1210) and its clamping bar (1211) to move down, the clamping air claw (1210) closes, and the clamping bar (1211) clamps the protective sticker (18). 2.12) The telescopic end of the No. 3 telescopic mechanism extends, driving the shearing claw (1213) and the shearing blade (1212) installed on it to move down. The shearing blade closes and cuts off the protective sticker (18) on the right edge of the fireproof composite board. 2.13) The piston rod of the first double-rod cylinder (15) extends, pushing the paper-drawing assembly (12) to move in the longitudinal center line of the base plate (11.1) away from the main support (11), while the piston rod of the double-rod cylinder (19) retracts. 2.14) The vacuum suction cup (34) is inflated, releasing the adsorption on the fireproof composite board. The telescopic end of the fourth telescopic mechanism of the fixing component arranged on the base plate (11.1) of the main support (11) retracts, driving the horizontal mounting plate (33) and the vacuum suction cup (34) installed on it to move down. 3) The composite board conveying equipment transports the fireproof composite board to the protective sticker applicators (B) on the left and right sides; 4) The protective sticker applicator (B) lifts, positions, and fixes the fireproof composite board, and applies protective stickers to the outer edges of both sides. The specific process is as follows: 4.1) The telescopic end of the No. 7 telescopic mechanism extends, causing the lifting plate (84) to move upward relative to the crossbeam of the No. 8 bracket (81), thus lifting the fireproof composite panel. 4.2) Similar to the process of positioning, fixing and applying protective stickers on the front and rear sides of the fireproof composite board by the front and rear protective sticker applicator (A), the process of applying protective stickers on the left and right sides of the fireproof composite board by the left and right protective sticker applicator (B). 4.3) The telescopic end of the No. 7 telescopic mechanism retracts, causing the lifting plate (84) to move down relative to the crossbeam of the No. 8 bracket (81), and the fireproof composite board is placed on the composite board conveying equipment. 5) The composite panel conveying equipment moves the fireproof composite panel to the next work station.
