Description

Technical Field

[0001] The present invention relates to a mechanical processing equipment technology, in particular to an automatic gluing device for plates. Background Art

[0002] Surface gluing is a common processing method for sheet materials. As consumers' demands for sheet material quality become increasingly higher, higher requirements are placed on the sheet material gluing process. In the traditional sheet material production industry, the surface gluing process for sheet materials adopts single-sided gluing. For sheets that require multi-sided gluing and then laminating, the traditional processing steps require the addition of two sets of gluing mechanisms or multiple online gluing processes to complete the gluing and laminating of the sheets. That is, after the gluing machine applies glue to one side of the sheet, the sheet is transported to the designated location using a conveyor mechanism. The sheet is then manually removed from the conveyor mechanism and stacked. The two sheets that have been glued on one side are manually laminated to obtain a composite sheet.

[0003] However, the existing glue laying method has the following defects:

[0004] (1) Single-sided gluing may cause uneven gluing, internal voids or air bubbles, and affect the gluing quality of the board.

[0005] (2) The manual operation method of transferring the plates increases the labor intensity of the workers and reduces the production efficiency. In addition, the glued surface or the edge of the plates are easily damaged during the stacking and transportation process, which is not conducive to the subsequent bonding process and even increases the process of cutting defective products, thereby increasing the overall operating cost.

[0006] (3) The factory is equipped with multiple sets of glue coating machines, which occupy a large area and have high operating costs. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, one of the purposes of the present invention is to provide an automatic gluing device for plates. The present invention realizes the simultaneous gluing of the opposing surfaces of two plates by designing a double-station gluing mechanism, the structure of the plate B loading mechanism, and the coordination of the actions of other mechanisms. After the gluing is completed, the plates can be directly bonded together without the need to carry or transfer the plates. This avoids damage to the gluing surface or plate edges caused by manual transfer of the plates, prevents the production of defective products, reduces the subsequent processing steps for defective products, and reduces operating costs. At the same time, the efficiency and quality of plate gluing are improved. The entire automatic plate laying device occupies a small area, reducing overall operating costs.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention realizes simultaneous gluing of the opposite surfaces of the two plates by designing a double-station gluing mechanism, the structure of the B plate loading mechanism, and the coordination of the actions of other mechanisms. After the gluing is completed, the plates can be directly bonded together without the need to carry or transfer the plates, thus avoiding damage to the gluing surface or the edge of the plates caused by manual transfer of the plates, and thus no defective products are produced, reducing the subsequent processing steps for defective products and reducing operating costs. At the same time, the efficiency and quality of the plate gluing are improved; the entire automatic plate laying device occupies a small area, thereby reducing the overall operating costs.

[0022] (2) The present invention designs a plate-shaped manipulator that absorbs the plate by vacuuming, which can better protect the integrity and flatness of the plate and prevent the plate from being damaged by manual transfer. This transfer method is particularly suitable for thin plates, light cardboard, soft boards and other plates.

[0023] (3) The main function of the flanging assembly designed in the present invention is to pull the edge of the sheet upward to break the vacuum inside the sheet, thereby achieving a sheet separation effect. The sheet separation plate of the flanging assembly uses a vacuum extraction method to flip the sheet. The two sheet separation plates located on both sides of the vacuum plate suction cup of the present invention can use independent air cavities. The two sheet separation plates can be inactive, can be moved individually, or can be linked together to set the flanging action according to the characteristics of the sheet.

[0024] (4) The positioning mechanism of the present invention adopts an inclination angle + an array of universal rollers, which can greatly avoid edge damage caused by collision and pressing. When the plate is placed on the base frame, due to the action of the inclination angle and the array of universal rollers, the plate automatically moves toward the downward inclined side of the base frame and adheres to the shaping pusher or the retaining edge; the array of universal rollers provides a good distributed support force for the thin plate, ensuring that the plate is not easily deformed when placed, and at the same time ensuring that the friction resistance of the bottom surface of the plate is reduced to a minimum during shaping by the positioning mechanism. In addition, the hollow plate is driven up and down by the lifting component, and the hollow part avoids the universal roller. When the shaping pusher completes the positioning and limiting of the plate, the hollow plate lifts the plate from bottom to top, providing sufficient support area for the plate to prevent deformation, and at the same time providing sufficient support force for the next process plate-shaped robot to take the material and press down, further ensuring that the plate does not deform.

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] like Figure 1-13 As shown, an automatic gluing device for plates comprises a double-station gluing mechanism 1 having an A station and a B station, an A plate conveying mechanism 2 for conveying A plate A to the A station of the double-station gluing mechanism, a positioning mechanism 3 for positioning B plate B to a specified position, a B plate loading mechanism 4 for transferring B plate on the positioning mechanism to the B station of the double-station gluing mechanism, and a bonding conveying mechanism 5 for placing the glued B plate on the surface of the glued A plate to bond them to each other.

[0041] Specifically, if Figure 3-4As shown, the double-station gluing mechanism 1 includes a fixed frame 11, a bottom roller 12, a lower coating roller 13, an upper coating roller 14, a glue tank 15, and a glue barrel 16; the bottom roller 12, the lower coating roller 13, and the upper coating roller 14 are rotatably mounted on the fixed frame 11 through bearing seats 17 respectively; the lower coating roller 13 is located above the bottom roller 12, and a gap is left between the bottom roller 12 and the lower coating roller 13 for the A plate to pass through, which is used for gluing the upper surface of the A plate; the upper coating roller 14 is located above the lower coating roller 13, which is used for gluing the lower surface of the B plate; the glue tank 15 is installed at the lower part of the upper coating roller 14, and the lower surface of the upper coating roller 14 is immersed in the inside of the glue tank 15; a funnel hole group is provided at the bottom of the glue tank 15; the glue barrel 16 is installed below the bottom roller 12;

[0042] like Figure 8 As shown, the B-plate loading mechanism 4 includes a plate-shaped manipulator 41 and a manipulator moving module 42; the plate-shaped manipulator 41 is installed on the manipulator moving module 42, and is driven by the manipulator moving module 42 to grab the B-plate and move it to the upper surface of the upper coating roller 14 to realize the transportation and gluing of the B-plate.

[0043] The present invention realizes simultaneous gluing of the opposing surfaces of the two plates by designing a double-station gluing mechanism, the structure of the B plate loading mechanism 4, and coordinating with the actions of other mechanisms. After the gluing is completed, the plates can be directly bonded together without the need to carry or transfer the plates, thereby avoiding damage to the gluing surface or the edges of the plates caused by manual transfer of the plates, and thus no defective products are produced, reducing the subsequent process of cutting defective products and reducing operating costs. At the same time, the efficiency and quality of the plate gluing are improved; the entire automatic plate laying device occupies a small area, thereby reducing overall operating costs.

[0044] The process of synchronously coating the opposite surfaces of two plates with glue is as follows: the bottom roller 12 of the double-station gluing mechanism 1 is used to transport plate A, the lower coating roller 13 is used to apply glue or powder or other materials to the upper surface of plate A, and the upper coating roller 14 is used to apply glue or powder or other materials to the bottom surface of plate B; the coating action of plate B relies on the plate-shaped manipulator 41 of the plate B upper plate mechanism 4 to grab plate B, and then, through the control of the manipulator moving module 42, move plate B to the upper surface of the upper coating roller 14 and pass it at a certain speed, so that the upper coating roller 14 transfers the glue or powder to the bottom surface of plate B.

[0045] As a further preferred solution, Figure 3As shown, the dual-station gluing mechanism 1 also includes a cylinder assembly for adjusting the gap size between the bottom roller 12 and the lower coating roller 13. The cylinder assembly includes a downward-pressing cylinder 18 and a gluing slide 19. The cylinder's telescopic rod is fixedly connected to the bearing seat 17 on the lower coating roller 13. The gluing slide 19 is fixedly mounted on the fixed frame 11, and the bearing seat 17 is slidably mounted on the gluing slide 19 and moves up and down along the slider on the gluing slide 19 under the drive of the cylinder's telescopic rod. The cylinder assembly is provided to adjust the amount of glue applied to sheet A. Specifically, the downward-pressing cylinder 18 controls the center distance between the bottom roller 12 and the lower coating roller 13 to adjust the gap size.

[0046] As a further preferred solution, Figure 9-10 As shown, the plate-shaped manipulator 41 includes a vacuum plate-shaped suction cup 411, an exhaust duct 412 provided on the vacuum plate-shaped suction cup 411, and a vacuum pump 413 connected to the exhaust duct 412. The vacuum plate-shaped suction cup 411 is provided with an air lock valve 414, which is sealed or opened by a sealing assembly 415 to maintain or exhaust the vacuum in the air cavity within the vacuum plate-shaped suction cup 411. The present invention, by designing the plate-shaped manipulator 41, sucks the plate by vacuuming, which can better protect the integrity and flatness of the plate and prevent damage to the plate edge caused by manual transfer. This transfer method is particularly suitable for thin plates, lightweight cardboard, soft boards, and other plates.

[0047] As a further preferred solution, Figure 9 As shown, a sponge 416 is provided at the bottom of the vacuum plate-shaped suction cup 411. Due to its softness, easy conformability, and full coverage, the sponge 416 has strong adsorption, cushioning, and gripping effects on thin plates, oil-film plates, and special-shaped plates. The addition of the sponge 416 can better protect the plates and is suitable for gripping and transferring plates with a certain degree of inclination after being positioned by the positioning mechanism, providing a certain cushioning effect.

[0048] As a further preferred solution, Figure 10 As shown, the sealing assembly 415 includes a sealing sheet 4151, a sealing cylinder 4152, and a cylinder mounting seat 4153; the shape of the sealing sheet 4151 is adapted to the shape and size of the air locking valve 414; the telescopic rod of the sealing cylinder 4152 is fixedly connected to the sealing sheet 4151, the cylinder body of the sealing cylinder 4152 is fixed on the cylinder mounting seat 4153, and the cylinder mounting seat 4153 is fixed on the back of the vacuum plate-shaped suction cup 411. The function of the air locking valve 414 is to keep the vacuum pressure in the air cavity from being easily lost, and to exhaust the vacuum. The process of grabbing the plate requires the sealing assembly 415 to close the air locking valve 414 to concentrate the vacuum pressure in the air cavity. When releasing the plate, in order to avoid vacuum adsorption, the sealing assembly 415 needs to open the air locking valve 414 to exhaust the gas.

[0049] As a further preferred solution, Figure 9 As shown, the B plate upper plate mechanism 4 also includes a flanging assembly 43; the flanging assembly 43 includes a spreading plate 431 and a spreading cylinder 432, and the spreading plate 431 is movably connected to both sides of the vacuum plate-shaped suction cup 411; the cylinder body of the spreading cylinder 432 is movably installed on the back of the vacuum plate-shaped suction cup 411, and the telescopic rod of the spreading cylinder 432 is installed on the back of the spreading plate 431 through a connecting rod 433; the spreading plate 431 is turned outward by controlling the spreading cylinder 432 to break the vacuum adsorption between the plate and the vacuum plate-shaped suction cup 411. The flanging assembly 43 designed in the present invention mainly functions to pull the edge of the plate upward to break the vacuum inside the plate, thereby achieving a spreading effect. The spreading plate 431 of the present invention can use an existing flipping mechanism to achieve its flipping action, and can also flip the plate by vacuuming. Preferably, the two separating disks 431 on both sides of the vacuum plate suction cup 411 of the present invention can use independent air cavities. The two separating disks 431 can be inactive, can act individually, or can be linked together at the same time, and the flanging action can be set according to the characteristics of the plate.

[0050] As a further preferred solution, Figure 8 , Figure 11-12 As shown, the manipulator moving module 42 includes a Z-axis moving module 421 and an X-axis moving module 422; the plate-shaped manipulator 41 is installed on the Z-axis moving module 421 to enable the plate-shaped manipulator 41 to move up and down in the vertical direction; the Z-axis moving module is installed on the X-axis moving module 422 to enable the plate-shaped manipulator 41 to move back and forth in the horizontal direction.

[0051] The Z-axis moving module 421 of the present invention can be a moving module capable of realizing vertical lifting motion in the prior art, such as the cooperation between screw transmission components. The Z-axis moving module 421 of the present invention specifically adopts a tooth meshing transmission method to realize vertical lifting displacement. The Z-axis moving module 421 includes a first mounting frame 4211, a first slide 4212, a vertical slide 4213, and a Z-axis motor 4214; the first slide 4212 is fixedly mounted on the first mounting frame 4211; a slider is provided on one side of the vertical slide 4213, and the slider is cooperated with the first slide 4212 to move up and down in the vertical direction; the other side opposite to the vertical slide 4213 is provided with teeth arranged in the vertical direction; the power output end of the Z-axis motor 4214 is connected to a power gear that meshes with the teeth. The Z-axis motor 4214 rotates, driving the power gear to rotate, and through the meshing transmission of teeth and gears, drives the vertical slide 4213 to move up and down along the first slide 4212 and the first mounting frame 4211, and the plate-shaped manipulator 41 is fixed at the bottom of the vertical slide 4213, so that the plate-shaped manipulator 41 can be lifted and lowered along the vertical direction of the Z-axis.

[0052] The X-axis moving module 422 of the present invention can be a moving module that can realize horizontal left and right movement in the prior art. For example, the X-axis moving module 422 of the present invention includes a second mounting frame 4221, a translation slider 4222, a translation slide rail 4223, and an X-axis motor (not shown in the figure); the first mounting frame 4211 of the Z-axis moving module 421 is fixed on the second mounting frame 4221; the translation slider 4222 is installed at the bottom of the second mounting frame 4221, and the translation slide rail 4223 is installed on the upper plate frame 6 for installing the entire B plate upper plate mechanism 4; the X-axis motor is connected to the second mounting frame 4221 or the translation slider 4222 through transmission, and the transmission method can be screw transmission or tooth meshing transmission, so as to realize the horizontal movement of the plate-shaped manipulator 41 along the length direction of the horizontal slide rail, thereby realizing the transfer action of the plate.

[0053] As a further preferred solution, Figure 6-7As shown, the automatic gluing device for plates also includes a positioning mechanism 3 for positioning plate B to a specified position; the positioning mechanism 3 includes a base frame 31, an array of universal rollers 32, a hollow plate 33, a lifting assembly 34, and a shaping pusher 35; the base frame 31 is installed on the first conveying base frame 21 of the A plate conveying mechanism 2, and the side of the base frame 31 close to the double-station gluing mechanism 1 is a downward inclined side; the array of universal rollers 32 is installed on the base frame 31; the hollow plate 33 is provided with an array of through holes, and the hollow plate 33 is laid on the base frame 31 so that the array of universal rollers 32 protrude outside the array of through holes on the hollow plate 33; the lifting assembly 34 is arranged below the base frame 31, and the lifting assembly 34 passes through the base frame 31 and is transmission-connected to the bottom surface of the hollow plate 33; the shaping pusher 35 is installed on the periphery of the base frame 31. The main purpose of the present invention to perform positioning treatment before the B plate is put on the board is, on the one hand, to improve the uniformity of the B plate in the process of gluing by the double-station gluing mechanism 1, thereby avoiding coating leakage around the plate; on the other hand, to improve the accuracy of the alignment of the B plate and the A plate in the subsequent bonding process, thereby improving the quality of the gluing and bonding processing and improving the gluing quality of the composite plate.

[0054] In addition, since most of the existing positioning mechanisms 3 use centering tools, such as centering plates, to correct the position of the plate, especially for positioning and shaping thin plates, lightweight cardboard, glass and other easily deformed and fragile plates, it is easy to cause compression damage to the plate, thereby causing subsequent processing, such as a decrease in the processing quality of the bonding process. The positioning mechanism 3 of the present invention uses an inclination angle + an array of universal rollers 32 to greatly avoid edge damage caused by impact and compression. When the plate is placed on the base frame 31, due to the action of the inclination angle and the array of universal rollers 32, the plate automatically moves toward the downward inclined side of the base frame 31 and is attached to the shaping pusher 35 or the retaining edge; the array of universal rollers 32 provides a good distributed support force for the thin plate, ensuring that the plate is not easily deformed when placed, and at the same time ensuring that the friction resistance of the bottom surface of the plate is reduced to a minimum when the positioning mechanism 3 is shaping. The hollow plate 33 designed in addition is driven up and down by a lifting component 34 (the lifting component includes but is not limited to a cylinder, a motor or a reduction motor, or a worm elevator, etc.), and the hollow part avoids the universal roller. When the shaping pusher 35 completes the positioning and limiting of the plate, the hollow plate 33 supports the plate from bottom to top, providing sufficient support area for the plate to prevent deformation, and at the same time providing sufficient support force for the next process plate-shaped robot 41 to take the material and press down, further ensuring that the plate is not deformed.

[0055] As a further preferred solution, Figure 5As shown, the A plate conveying mechanism 2 includes a first conveying chassis 21, a first belt assembly mounted on the first conveying chassis 21; the first belt assembly includes a loading motor 22, a first driving wheel 23, a first driven wheel 24, and a first belt 25; the first belt 25 is sleeved between the first driving wheel 23 and the first driven wheel 24, and the loading motor 22 drives the first driving wheel 23 to rotate; the A plate conveying mechanism 2 also includes a first guide wheel assembly 26 and a first centering disc 27 arranged on one side of the first conveying chassis 21. As a further preferred embodiment, as Figure 13 As shown, the automatic gluing device for plates also includes a bonding conveying mechanism 5; the bonding conveying mechanism 5 includes a second conveying chassis 51 and a second belt assembly installed on the second conveying chassis 51; the second belt assembly includes a discharge motor 52, a second driving wheel 53, a second driven wheel 54, and a second belt 55; the second belt 55 is arranged between the second driving wheel 53 and the second driven wheel 54, and the discharge motor 52 drives the second driving wheel 53 to rotate; the bonding conveying mechanism 5 also includes a second guide wheel assembly 56, a second centering plate 57 and front and rear pushers (not shown in the figure) located in the forward direction, which are arranged on one side of the second conveying chassis 51. The above-mentioned correction components are arranged to achieve consistency in the front, back, left and right positions of the plates during the bonding process, thereby improving the bonding quality of the plates.

[0056] The A-sheet of the present invention is conveyed before gluing by the A-sheet conveying mechanism 2, and the upper surface of the A-sheet is glued by the A-station of the double-station gluing mechanism 1. After gluing, the sheet is sent out by the belt assembly of the bonding conveying mechanism 5, and finally the bonding process is completed on the bonding conveying mechanism 5. In terms of power transmission, the bottom roller 12, the lower coating roller 13, and the upper coating roller 14 on the double-station gluing mechanism are not powered and rotate passively. The forward power of the sheet passing through the gluing station depends on the active input of the A-sheet conveying mechanism 2 and the active output of the bonding conveying mechanism 5. The position correction of the A-sheet during the gluing and bonding process is mainly achieved through the guide wheel assembly and the centering disk provided on the A-sheet conveying mechanism 2 and the bonding conveying mechanism 5, thereby ensuring that the position of the A-sheet remains consistent during the gluing process.

[0057] The automatic sheet laying device of the present invention is used to simultaneously complete the gluing and laminating processes for two sheets, A and B, to produce a composite sheet with high-quality gluing and greatly reduced sheet waste. Sheets A and B can be made of the same material or different materials. The operating process of this automatic sheet laying device is as follows:

[0059] The A sheet is conveyed to the A station of the double-station gluing mechanism 1 by the A sheet conveying mechanism 2; the position of the B sheet is first corrected by the positioning mechanism 3 to improve the position accuracy of the subsequent sheet transfer, gluing process, and laminating process; the B sheet after position correction is grasped by the plate-shaped manipulator 41 of the B sheet loading mechanism 4, and then moved to the B station of the double-station gluing mechanism 1 to complete the gluing preparation action;

[0060] (2) Steps of double-station gluing:

[0061] After the positions of plate A and plate B are prepared, glue or powder or other materials are applied to the upper surface of plate A by the lower coating roller 13 of the double-station coating mechanism 1, and glue or powder or other materials are applied to the bottom surface of plate B by the upper coating roller 14 of the double-station coating mechanism 1; wherein, loading and gluing are a continuous process.

[0062] (3) Lamination and conveying steps:

[0063] After the A and B plates are coated with glue, the A plate is sent out through the belt assembly of the bonding conveyor mechanism 5, and the B plate is further transferred to the top of the bonding conveyor mechanism 5 by the plate-shaped robot 41. The X-axis moving module 422 controls the plate-shaped robot 41 to adjust the horizontal position, and the Z-axis moving module 421 controls the plate-shaped robot 41 to adjust the vertical position, and the B plate is placed on the upper surface of the A plate to complete the bonding process. Finally, the finished product is sent out by the belt assembly of the bonding conveyor mechanism 5.
