Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of die-cutting equipment, specifically a sponge die-cutting plate bonding device based on beam positioning. Background Technology
[0002] Sponge die-cutting plate bonding technology, as a core supporting process in precision die-cutting, is widely used in printing and packaging, electronic auxiliary material processing, automotive interior manufacturing, medical consumable production, and other fields. Its bonding accuracy directly determines the uniformity of force on the die-cutting blade, the demolding effect, and the quality of the product cut. In the die-cutting of products such as corrugated boxes, self-adhesive labels, electronic foam, and automotive sound insulation, the sponge die-cutting plate (die-cutting plate spring pad) needs to be precisely bonded to the die surface. By providing uniform rebound force, it ensures complete material cutting and smooth edges, while avoiding problems such as blade jamming, blade sticking, and point breakage. It is a key link in improving die-cutting efficiency and yield. As modern manufacturing develops towards high precision, large scale, and personalization, the complexity of the contours and the requirements for dimensional accuracy of die-cutting products continue to increase, placing higher standards on the bonding position accuracy, spacing consistency, and adaptability flexibility of the sponge die-cutting plate.
[0003] Traditional sponge blade bonding devices mostly rely on methods such as measuring with a tape measure, positioning with a ruler, or visual aiming. Positioning errors are generally on the order of centimeters and are easily affected by human error, ambient light interference, and operator experience, leading to insufficient alignment accuracy between the sponge blade and the die-cutting blade. Misalignment in the bonding position causes uneven pressure transmission during die-cutting. In some areas, the sponge protrudes excessively from the blade, causing excessive material compression; in other areas, excessive bonding gaps lead to poor demolding, resulting in waste material blockage, burrs on the product cut, and in severe cases, accelerated blade wear, reducing product yield and production efficiency. More importantly, this manual-assisted positioning operation mode is highly dependent on the operator's proficiency and practical experience, which is extremely unfriendly to novice operators. Novices lack long-term accumulated positioning skills and feel, making it difficult to learn and requiring a long adaptation period. They often need a long period of training to initially master the basic operations, and in actual operation, they are prone to problems such as positioning deviation and calibration errors, requiring a lot of time to repeatedly try, adjust and correct. They may even damage the sponge blade plate and contaminate the die surface due to improper operation, further prolonging the bonding operation time of a single die. At the same time, the low efficiency of novice operators not only significantly increases the company's personnel training costs, but also slows down the operation progress of the entire production line. Especially in the scenario of small-batch, multi-batch personalized production, the frequent product changes and the low efficiency of novice operators combine to result in poor production continuity, extended cycle, and difficulty in ensuring bonding consistency. It is impossible to achieve uniformity of sponge bonding parameters for each die in mass production, which further restricts the stability of die-cut product quality.
[0004] Therefore, it is necessary to invent a sponge blade bonding device based on beam positioning to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to solve the problem that the sponge strip is easily misplaced, incorrectly pasted, or missed when pasting due to visual fatigue and operational errors by the operator during use of existing devices, and to propose a sponge blade pasting device based on beam positioning.
[0006] To achieve the above objectives, the present invention employs the following technology: a sponge blade bonding device based on beam positioning, comprising a worktable with a PLC controller mounted on its surface, on which a blade and a sponge strip are mirror-mounted, and two L-shaped positioning baffles respectively abutting the sides of the blade and the sponge strip are also mounted on the worktable, with insertion holes at each of the four corners of the bottom of the worktable, and a support base with positioning rods fixedly connected to the four corners of the top of the worktable is located below the worktable, the worktable and the support base are connected and positioned through the cooperation of the insertion holes and the positioning rods, and a mounting base is threaded to one end of the worktable, on which an adjustment component is mounted, and a projection component is fixedly connected to the adjustment component.
[0007] As a further description of the above technical solution: the surface of the workbench is made of cold-rolled steel plate, and a magnetic block is fixedly connected to the bottom of the L-shaped positioning baffle. The L-shaped positioning baffle is attracted and positioned to the surface of the workbench by the magnetic block. A handle is also fixedly connected to the L-shaped positioning baffle.
[0008] As a further description of the above technical solution: the bottom of the bearing seat is fixedly connected to a base via a support column, and support screws are threaded to the four corners of the base. Support feet are fixedly connected to the bottom of the support screws, and handwheels are fixedly connected to the top of the support screws.
[0009] As a further description of the above technical solution: the adjustment component includes a stand fixedly connected to the mounting base, two limiting slide rods fixedly connected to the inner side of the stand, and a servo motor with an output end fixedly connected to an adjustment screw at the top of the stand. One end of the adjustment screw is rotatably connected to the mounting base through a bearing.
[0010] As a further description of the above technical solution: the adjusting screw is located between the two limiting slide rods, and a sliding seat is threaded onto the outer side of the adjusting screw. The limiting slide rod passes through the sliding seat and is slidably connected to the sliding seat.
[0011] As a further description of the above technical solution: the projection assembly includes a mounting plate welded to one end of the sliding seat, and a dual-light-path projector is bolted to the mounting plate.
[0012] As a further description of the above technical solution: the projection lens of the dual-light-path projector is vertically downward and located directly above the worktable, and the projection beam pattern of the dual-light-path projector is divided into a sponge positioning area and a blade-plate bonding area.
[0013] As a further description of the above technical solution: multiple sponge strips of the same shape and size as the blade are placed inside the sponge strip plate.
[0014] As a further description of the above technical solution, the size and position of the positioning rod match the socket, and the PLC controller is electrically connected to each electrical component.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention uses an L-shaped positioning baffle with magnetic blocks to fix the L-shaped positioning baffle to the workbench during actual use. The blade and sponge strip are then quickly positioned at a fixed location on the workbench, forming a standardized placement benchmark. This avoids positional deviations caused by manual placement from the outset. Combined with the partitioned positioning beams projected by a dual-light-path projector, the sponge positioning area and the blade bonding area are clearly delineated. Operators do not need to rely on experience or visual comparison; they only need to follow the beam guidance to accurately bond the sponge strip and blade. This effectively eliminates problems such as incorrect bonding, missing bonding, and misalignment. It simplifies the operation process, shortens the operation time for a single set of workpieces, and ensures that the bonding position of all products is uniform, greatly improving the stability of bonding operations and the consistency of finished product quality.
[0016] 2. This invention features an adjustable component, allowing the projection component to be vertically raised and lowered via a servo motor-driven sliding seat. This adapts to the processing needs of blades and sponge strips of different sizes and thicknesses, covering the operation of multiple product specifications without the need to change special tooling. The support seat achieves overall horizontal adjustment through support screws and support feet. Combined with the precise docking structure of the positioning rod and the insertion hole, it ensures that the worktable remains stable at all times, avoiding the impact of uneven ground on projection positioning accuracy. At the same time, the height of the worktable can be adjusted via the support screws, thus accommodating users of different heights. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Reference Figures 1-5 This embodiment provides a sponge blade bonding device based on beam positioning, including a worktable 1 with a PLC controller 11 on its surface. A blade 12 and a sponge strip 13 are mirror-mounted on the worktable 1. Multiple sponge strips of the same shape and size as the blade 12 are placed inside the sponge strip 13. The worktable 1 is also provided with two L-shaped positioning baffles 14 that are respectively attached to the sides of the blade 12 and the sponge strip 13. The surface of the worktable 1 is made of cold-rolled steel. A magnetic block 15 is fixedly connected to the bottom of the L-shaped positioning baffle 14. The L-shaped positioning baffle 14 is attracted and positioned to the surface of the worktable 1 by the magnetic block 15. A handle 16 is also fixedly connected to the L-shaped positioning baffle 14. The PLC controller 11 is electrically connected to various electrical components. A mounting base 3 is threaded to one end of the worktable 1. An adjustment component 4 is provided on the mounting base 3. A projection component 5 is fixedly connected to the adjustment component 4.
[0021] See attached document Figure 1 and Figure 2 The workbench 1 has four holes at the bottom corners. The workbench 1 has a support base 2 with positioning rods 26 fixedly connected to the top four corners. The workbench 1 and the support base 2 are connected and positioned by the cooperation of the holes and the positioning rods 26. The size and position of the positioning rods 26 match the holes. The support base 2 has a base 22 fixedly connected to the bottom by a support column 21. The base 22 has a support screw 23 threadedly connected to the four corners. The support screw 23 has a support foot pad 24 fixedly connected to the bottom and a handwheel 25 fixedly connected to the top.
[0022] See attached document Figure 1 and Figure 5 The adjustment assembly 4 includes a stand 41 fixedly connected to the mounting base 3. Two limiting slide rods 42 are fixedly connected to the inner side of the stand 41. A servo motor 44 with an output end fixedly connected to an adjustment screw 43 is provided on the top of the stand 41. One end of the adjustment screw 43 is rotatably connected to the mounting base 3 through a bearing. The adjustment screw 43 is located between the two limiting slide rods 42. A sliding seat 45 is threaded onto the outer side of the adjustment screw 43. The limiting slide rods 42 pass through the sliding seat 45 and are slidably connected to the sliding seat 45. The projection assembly 5 includes a mounting plate 51 welded to one end of the sliding seat 45. A dual-light-path projector 52 is bolted to the mounting plate 51. The projection lens of the dual-light-path projector 52 is vertically downward and located directly above the worktable 1. The projection beam pattern of the dual-light-path projector 52 is divided into a sponge positioning area and a blade plate 12 contact area.
[0023] Therefore, in practical use, the equipment is first debugged as a whole. The support seat 2 and the base 22 are placed on the work site. The handwheels 25 at the four corners of the base 22 are rotated to drive the support screws 23 to rotate. The device is adjusted to a horizontal state by using the support feet 24. Then, the insertion hole at the bottom of the workbench 1 is precisely aligned with the positioning rod 26 at the top of the support seat 2 to complete the stable assembly of the workbench 1 and the support seat 2, ensuring that the workbench surface is not tilted or shaken. Next, the workpiece is positioned and fixed. The operator attaches the L-shaped positioning baffle 14 to the workbench 1 according to the size and working position of the blade plate 12 and the sponge strip 13. Then, the blade plate 12 and the sponge strip 13 are placed inside the L-shaped positioning baffle 14 and fitted together to prevent displacement of the blade plate 12 and the sponge strip 13 during operation. Next, the projection component 5 is adjusted. The servo motor 44 on the top of the stand 41 is started by the PLC controller. The motor drives the adjusting screw 43 to rotate, which drives the threaded sliding seat 45 to move smoothly vertically along the two limit slide rods 42. This adjusts the height of the mounting plate 51 and the dual-light-path projector 52, so that the beam projected by the projector can completely cover the working area of the workbench 1. Then, the precision bonding operation is carried out. The dual-light-path projector 52 projects a beam vertically downward, clearly dividing the sponge positioning area and the bonding area of the blade 12. The operator takes out the sponge strip of the corresponding size from the sponge strip plate 13 and precisely pastes the sponge strip to the designated bonding position of the blade 12 according to the position marked by the beam. The entire operation is completed by relying on the beam guidance, without the need for manual visual comparison. After the bonding operation of a single set of blades 12 is completed, the bonded finished product can be directly removed, and a new blade 12 and sponge strip 13 can be replaced. By repeating the steps of workpiece positioning, projection adjustment, and precise bonding, continuous and large-scale sponge blade bonding operation can be achieved. The entire process is stable, precise in positioning, and easy to operate.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
