Description

Technical Field

[0001] The present invention relates to the technical field related to conveying devices, and in particular to an automatic conveying device for a semi-automatic laser die-cutting machine. Background Art

[0002] Laser die-cutting machine mainly uses the high thermal energy of laser to perform high-depth ablation on the die-cutting board to form a knife seam. It has the advantages of straight cutting seam, uniform seam width, low cost and high efficiency. It is the best choice to replace the traditional production of die-cutting boards. It is an important equipment for post-printing packaging processing and forming. It is mainly used for die-cutting, creasing and hot stamping operations of cardboard, corrugated board, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone rubber pads, etc.

[0003] However, during the conveying process of flexible materials or thin plate materials, in order to ensure the stability of material conveying, guide pressure plates, pressure wheels and other structures are usually set on the upper end or side of the material. Existing equipment generally has design defects in the pressing, guiding and supporting structures, which directly affect the cutting accuracy and material transmission stability.

[0004] On the one hand, the pressing force of the pressing device is unevenly distributed, which is mainly due to the insufficient rigidity or unreasonable arrangement of the pressing wheel or pressing plate, which can easily cause the material to bulge and slip, and fail to stick to the conveying surface, thereby causing positioning errors; on the other hand, the support width of the guide structure is narrow, and the edge constraint of the flexible material is insufficient. Especially during high-speed transmission, the edge of the material is prone to deflection, increasing the cutting error. In addition, when conveying longer materials, due to the lack of support from the rigid support plate or roller below, the material sags under its own weight and destroys the parallelism with the laser focal plane, thereby affecting the cutting quality; even worse, the upper pressure structure with single-point or narrow surface compression may also cause local bending or stress concentration of the material, resulting in wrinkles.

[0005] The superposition of these structural problems has become a key obstacle to improving die-cutting accuracy and ensuring stable equipment operation. Summary of the Invention

[0054] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0055] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0056] like Figures 1-8 As shown, an automatic conveying device for a semi-automatic laser die-cutting machine includes:

[0057] A die-cutting mechanism 1 and a conveying mechanism 2 provided at the lower end of the die-cutting mechanism 1, wherein the conveying mechanism 2 reciprocates to realize bidirectional loading and unloading;

[0058] Both sides of the conveying mechanism 2 are both loading areas and unloading areas. For example, when the conveying mechanism 2 on the left is preparing for loading, the conveying mechanism 2 on the right has completed the processing of the material and is ready to unload. Subsequently, when the conveying mechanism 2 on the left has completed the processing of the material and is ready to unload, the conveying mechanism 2 on the right is ready to load. This reciprocating left and right operation can avoid the negative pressure suction pipe 43 from becoming entangled and can improve work efficiency. When in use, a loading robot or other loading tooling can be used on both sides of the conveying mechanism 2.

[0059] The upper end of the conveying mechanism 2 is provided with a plurality of adsorption mechanisms 3 arranged in an array along its transmission direction;

[0060] The adsorption mechanism 3 includes a main unit 31, an adsorption assembly 32, a connecting air pipe 33, and a shielding unit 34. The adsorption assembly 32 is provided in several groups and arranged perpendicularly to the transmission direction of the conveying mechanism 2. The groups of adsorption assemblies 32 are interconnected by connecting air pipes 33. The main unit 31 is provided with a placement groove 311 for placing the shielding unit 34 at a position corresponding to each group of adsorption assemblies 32. When the shielding unit 34 is placed in the placement groove 311, it will shield the suction unit 323 at the upper end of the adsorption assembly 32.

[0061] A negative pressure suction mechanism 4 is further provided on the outside of the conveying mechanism 2 , and the negative pressure suction mechanism 4 is provided with negative pressure suction pipes 43 corresponding to each group of the connecting air pipes 33 , and the negative pressure suction pipes 43 move synchronously with the connecting air pipes 33 .

[0062] Among them, the adsorption mechanism 3 arranged in an array has a grid layout to form a continuous adsorption area. The connecting air pipe 33 refers to a flexible pipeline that runs through adjacent adsorption components 32, such as a polyurethane hose, which is used to balance the negative pressure value of each adsorption unit 321. The shielding unit 34 includes a modular blocking block that can be embedded in the placement groove 311, which can adopt a magnetic fixation or snap-on structure to selectively close a specific adsorption area. The synchronously moving negative pressure suction pipe 43 refers to a telescopic pipe linked to the conveying mechanism 2, such as a corrugated pipe connected by a track sliding, to ensure real-time matching of the adsorption system and the conveying position.

[0063] Specifically, when the conveying mechanism 2 is started, it drives the adsorption component 32 to move synchronously, and the negative pressure suction mechanism 4 provides negative pressure to the adsorption component 32 through the connecting air pipe 33. When the material enters the adsorption area, the array adsorption mechanism 3 forms a uniform adsorption force to make the material close to the conveying surface. For areas that need to avoid die-cutting processing, the operator embeds the shielding unit 34 into the corresponding placement groove 311 to close the suction port of the adsorption component 32 at this location to avoid waste of negative pressure and prevent local deformation of the material. After the shielding unit 34 is installed, its supporting structure automatically adjusts the height to maintain the flatness of the conveying surface. The negative pressure suction pipe 43 extends and contracts synchronously with the displacement of the conveying mechanism 2, eliminating the pipeline distortion caused by the traditional fixed interface and ensuring continuous and stable adsorption force.

[0064] Further, if Figure 4-Figure 8 As shown, the adsorption component 32 includes an adsorption unit 321, an air suction channel 322 and an air suction unit 323, and several groups of the adsorption units 321 are integrally formed; the air suction channel 322 is arranged at the lower end of the interior of the adsorption unit 321 and is interconnected with the connecting air pipe 33; the air suction unit 323 is arranged at the upper end of the air suction channel 322 and is connected to the air suction channel 322.

[0065] Among them, the adsorption unit 321 refers to a rigid structure formed as a whole by a mold, which can be specifically realized by an aluminum alloy extrusion molding process. A continuous air flow channel network is formed inside it to eliminate the gap error caused by the split assembly. The suction channel 322 refers to an internal cavity structure extending along the length direction of the adsorption unit 321. Specifically, CNC machining can be used to form a through-hole channel, which is used to evenly distribute the negative pressure airflow input by the connecting air pipe 33 to each adsorption area. The suction unit 323 refers to an airflow control module embedded in the top of the adsorption unit 321. Specifically, it can be realized by a copper suction nozzle assembly with a sealing ring, which is connected to the suction channel 322 through a vertical through hole, so that the negative pressure acts directly on the material surface.

[0066] Specifically, the adsorption unit 321 is formed into a rigid frame through integral molding to resist deformation caused by external loads during material transmission. The suction channel 322 extends longitudinally along the adsorption unit 321, and the air pressure balance of each adsorption point is achieved through the equal-section design of the internal cavity. The suction unit 323 is embedded in the top of the adsorption unit 321 in the form of an array, and its bottom end forms a vertical connecting structure with the suction channel 322, so that the negative pressure airflow is layered controlled: the suction channel 322 completes the horizontal airflow distribution, and the suction unit 323 realizes the longitudinal adsorption execution. When the negative pressure suction mechanism 4 is started, the airflow enters the suction channel 322 from the connecting air pipe 33, and is evenly transmitted to each suction unit 323 through a vertical path, forming a uniform adsorption force field covering the surface of the material.

[0067] Further, if Figures 9-12As shown, the air suction unit 323 includes a mounting block 3231 and an air suction pipe 3232 disposed inside the mounting block 3231 , and the lower end of the air suction pipe 3232 extends out of the mounting block 3231 and into the interior of the air suction channel 322 ;

[0068] The adsorption unit 321 is provided with a through slot 312 at a position corresponding to the mounting block 3231 , which is matched with the mounting block 3231 .

[0069] Among them, the mounting block 3231 refers to a rigid structural component used to support the intake pipe 3232, which can be specifically formed by aluminum alloy or engineering plastic. A through hole is provided inside it for fixing the intake pipe 3232. The rigidity of the mounting block 3231 can prevent the intake pipe 3232 from shifting under the action of negative pressure, ensuring that it is aligned with the axis of the intake channel 322.

[0070] The intake pipe 3232 refers to an air flow transmission pipe embedded in the mounting block 3231. Specifically, a stainless steel pipe or a hard plastic pipe can be used. The lower end of the intake pipe 3232 extends to the inside of the intake channel 322 to form an embedded connection. The extension length of the intake pipe 3232 can be 5-10 mm. The physical limit is used to increase the contact area with the intake channel 322 to reduce the risk of air flow leakage.

[0071] Specifically, the mounting block 3231 is formed through mechanical processing to have an outer dimension that matches the through slot 312 of the adsorption unit 321. When the mounting block 3231 is assembled to the through slot 312 of the adsorption unit 321, the lower end of the intake pipe 3232 is precisely inserted into the interior of the intake channel 322 to form a double sealing structure. Under the action of negative pressure, the contact surface between the intake pipe 3232 and the intake channel 322 produces a self-tightening effect due to the air pressure difference, further enhancing the sealing performance. As a result, the air flow path inside the adsorption component 32 is strictly limited, avoiding the negative pressure loss caused by the connection gap, and ensuring that the intake volume of each adsorption unit 321 is evenly distributed.

[0072] The side walls of the through slot 312 contact the side surfaces of the mounting block 3231 to form a physical limit, limiting the horizontal displacement of the mounting block 3231. The bottom surface of the through slot 312 contacts the bottom of the mounting block 3231. During the assembly process, the mounting block 3231 is embedded along the axial direction of the through slot 312, and the intake pipe 3232 is synchronously inserted into the intake channel 322 along with the mounting block 3231. The geometric accuracy of the through slot 312 is controlled within ±0.05 mm to ensure that the mounting block 3231 coincides with the axis of the intake channel 322 after being embedded, thereby avoiding misalignment of the intake pipe 3232 and the intake channel 322.

[0073] Further, if Figure 5-10As shown, the adsorption unit 321 is further provided with a mounting groove 313 at a position corresponding to the lower end of the mounting block 3231, and a multi-stage supporting unit 5 is provided inside the mounting groove 313;

[0074] The multi-stage support unit 5 includes a lower support portion 51, a transition portion 52 and an upper support portion 53 which are integrally formed;

[0075] When the upper support portion 53 is used to support the mounting block 3231 , the upper surface of the mounting block 3231 is flush with the upper surface of the adsorption unit 321 ;

[0076] When the lower support portion 51 is used to support the mounting block 3231 , a recessed portion is left between the upper surface of the mounting block 3231 and the upper surface of the adsorption unit 321 .

[0077] Among them, the installation groove 313 refers to a groove 3411 structure arranged at the bottom of the adsorption unit 321 and corresponding to the position of the installation block 3231. It can be formed by machining or casting, and is used to accommodate the multi-level support unit 5 and provide a fixed space for it. The multi-level support unit 5 refers to a structure with multiple support surfaces of different heights, for example, it is composed of a stepped support plate, which can be made of metal or high-strength plastic material, and provides adjustable rigid support for the installation block 3231 through support surfaces at different levels.

[0078] Specifically, the mounting groove 313 is opened at the bottom of the adsorption unit 321, which is directly below the core force-bearing area of ​​the mounting block 3231. The multi-stage support unit 5 is embedded in the mounting groove 313 and contacts the mounting block 3231. When the mounting block 3231 needs to be kept flush with the surface of the adsorption unit 321, the upper support surface of the multi-stage support unit 5 is selected as the supporting reference; when a recessed portion needs to be formed to accommodate the shielding unit 34, the multi-stage support unit 5 switches to the lower support surface, so that the mounting block 3231 is lowered to a preset height. The switching of the support level is achieved by adjusting the contact position of the multi-stage support unit 5 and the mounting block 3231, thereby ensuring that the mounting block 3231 can obtain a stable support force transmission path under different working conditions.

[0079] The lower support portion 51 refers to the load-bearing section located at the bottom of the support structure, which can be specifically implemented by a rectangular block structure and is used to bear the load of the mounting block 3231 in a low-position state. The transition portion 52 refers to the intermediate transition area connecting the lower support portion 51 and the upper support portion 53, which can be specifically implemented by an inclined surface or an arc surface structure and is used to guide the stress transfer when the support position is switched. The upper support portion 53 refers to the load-bearing section located at the top of the support structure, which can be specifically implemented by a platform-like structure and is used to maintain the planar consistency of the mounting block 3231 and the adsorption unit 321 in a high-position state. The recessed portion refers to the cavity area formed after the mounting block 3231 sinks, which is used to provide an accommodation space for the baffle 342.

[0080] Specifically, when it is necessary to keep the surface of the adsorption unit 321 flat, the mounting block 3231 is placed on the top of the upper support part 53. At this time, the mounting block 3231 and the adsorption unit 321 form a continuous plane together to avoid offset due to surface protrusions or depressions during material transmission. When it is necessary to install the shielding unit 34, the mounting block 3231 is switched to the top of the lower support part 51. At this time, the mounting block 3231 sinks to form a recessed part. After the shielding plate 342 is embedded in the recessed part, its surface remains flush with the adsorption unit 321. The one-piece molding design of the support structure eliminates the assembly gap of the split structure, ensuring the positioning accuracy when the support height is switched.

[0081] Further, if Figures 9-11 As shown, the multi-stage support unit 5 further includes at least one set of connecting rod units 54, and the connecting rod units 54 are integrally formed with the lower support portion 51, the transition portion 52 and the upper support portion 53;

[0082] The connecting rod unit 54 includes a connecting rod portion 541 and an arc portion 542 connected to the connecting rod portion 541;

[0083] One end of the multi-stage supporting unit 5 away from the placement groove 311 is disposed inside the installation groove 313 via a buffer spring 543 .

[0084] Among them, the connecting rod unit 54 refers to a component that rigidly connects the lower support part 51, the transition part 52 and the upper support part 53. Specifically, it can be realized by integral casting or injection molding of metal materials, and is used to enhance the overall structural strength of the multi-stage support unit 5 and avoid dislocation when each support part is subjected to force. The arc portion 542 refers to a curved structure connected to the end of the connecting rod part 541, and can be specifically realized by elastic material or thin-walled structure. When the blocking block 341 is squeezed, the pressure is absorbed through elastic deformation, thereby providing a buffer space for the position switching of the multi-stage support unit 5. The buffer spring 543 refers to an elastic element arranged in the mounting groove 313, and can be specifically realized by a coil spring or a disc spring. It is used to provide a reset force after the multi-stage support unit 5 switches its position to restore it to its initial state.

[0085] Specifically, when the blocking block 341 is not placed, the buffer spring 543 is in a naturally extended state, pushing the upper support portion 53 of the multi-stage support unit 5 to contact the mounting block 3231. At this time, the upper surface of the mounting block 3231 is flush with the adsorption unit 321. When the blocking block 341 is pressed into the placement groove 311, the blocking block 341 squeezes the arc portion 542, forcing the connecting rod unit 54 to drive the multi-stage support unit 5 as a whole to move away from the placement groove 311. At this time, the lower support portion 51 contacts the mounting block 3231, and the mounting block 3231 sinks to form a recessed portion. During this process, the arc portion 542 offsets the impact force through elastic deformation, and the connecting rod portion 541 keeps the supporting portions moving synchronously. The buffer spring 543 is compressed to store elastic potential energy. When the blocking block 341 is removed, the buffer spring 543 releases the potential energy, pushing the multi-stage support unit 5 to return to its initial position.

[0086] Further, if Figure 5-Figure 8 As shown, the shielding unit 34 includes a shielding block 341 and a shielding plate 342 fixedly connected to the shielding block 341;

[0087] Before the blocking block 341 is placed inside the placement groove 311 , the upper support portion 53 is used to support the installation block 3231 ;

[0088] After the blocking block 341 is placed inside the placement groove 311, the blocking block 341 squeezes the arc portion 542 and drives the multi-stage support unit 5 away from the blocking block 341. At this time, the lower support portion 51 is used to support the mounting block 3231, and the blocking plate 342 will fill the position of the recessed portion, and the upper surface of the blocking plate 342 is flush with the upper surface of the adsorption unit 321.

[0089] Among them, the blocking block 341 refers to a rigid component used to trigger the switching of the support structure, which can be specifically implemented by an aluminum alloy or engineering plastic block, and its bottom shape forms an interference fit with the placement groove 311. The component drives the multi-stage support unit 5 to produce displacement through mechanical contact, wherein the blocking plate 342 refers to a flat cover rigidly connected to the blocking block 341, which can be specifically implemented by a thin plate with the same surface material as the adsorption unit 321, and its thickness is equal to the depth of the recessed part, which is used to fill the gap formed by the sinking of the mounting block 3231, wherein the multi-stage support unit 5 refers to an elastic structure with a stepped support surface, which can be specifically implemented by stamping a spring steel sheet, and the curvature radius of the arc portion 542 matches the edge of the blocking block 341, and the height switching of the support surface is achieved through elastic deformation.

[0090] Specifically, when the blocking block 341 is not installed, the upper support portion 53 of the multi-stage support unit 5 lifts the mounting block 3231 to a level with the adsorption unit 321. When the blocking block 341 is inserted into the placement slot 311, its sidewall contacts and squeezes the curved portion 542 of the multi-stage support unit 5, forcing the entire support unit to move away from the blocking block 341. At this time, the lower support portion 51 replaces the upper support portion 53 to support the mounting block 3231, causing the mounting block 3231 to sink and form a recessed portion. The shielding plate 342 fixed to the blocking block 341 simultaneously moves to above the recessed portion. The thickness of the plate just fills the recessed space, restoring the overall adsorption surface to a flat state. This process achieves the synchronous conversion of the support state and the blocking action through purely mechanical linkage, without the need for an additional power device.

[0091] Further, if Figure 5 As shown, the placement groove 311 is provided with an adsorption member 6, and the blocking block 341 is detachably provided inside the placement groove 311 through the adsorption member 6;

[0092] At least one set of grooves 3411 is defined at the upper end of the shielding block 341 .

[0093] Among them, the adsorption part 6 refers to an adsorption structure set in the placement groove 311 for fixing the blocking block 341, which can be specifically implemented by a permanent magnet or an electromagnetic adsorption component 32, and maintains the position stability of the blocking block 341 in a vibration environment through adsorption force.

[0094] The groove 3411 refers to a recessed structure provided at the upper end of the shielding block 341 , which may be implemented by a U-shaped groove or a rectangular groove. The shielding block 341 can be disassembled by lever-type by inserting a tool into the reserved space.

[0095] Specifically, the blocking block 341 is adsorbed into the placement slot 311 by the magnetic force of the adsorption member 6 and remains fixed during the operation of the die-cutting machine to avoid displacement due to vibration. When maintenance is required, the operator inserts a tool into the groove 3411 and uses the torque generated by the prying tool to overcome the adsorption force and remove the blocking block 341 from the placement slot 311. During this process, the depth and width of the groove 3411 are designed to adapt to the size of standard tools, such as screwdrivers or special pry bars, to ensure the convenience of the disassembly operation. The contact surface between the blocking block 341 and the placement slot 311 adopts a flat processing technology to evenly distribute the adsorption force and avoid deformation caused by local stress concentration.

[0096] Further, if Figure 1-Figure 3 As shown, the negative pressure suction mechanism 4 includes a negative pressure suction component 41, a transmission unit 42 arranged on one side of the negative pressure suction component 41 and working synchronously with the conveying mechanism 2, and several groups of negative pressure suction pipes 43 are fixedly arranged on the transmission unit 42.

[0097] The negative pressure suction component 41 refers to a device for generating negative pressure, which can be specifically implemented by a vacuum pump or a centrifugal fan, and its function is to provide a stable negative pressure source for the adsorption mechanism 3 .

[0098] The transmission unit 42 refers to a power transmission device that matches the motion trajectory of the conveying mechanism 2. Specifically, it can be implemented by chain transmission, synchronous belt or linear motor. Its synchronization design ensures that the negative pressure suction pipe 43 and the conveying mechanism 2 keep moving at the same speed.

[0099] The negative pressure suction pipe 43 refers to the pipeline connecting the negative pressure suction component 41 and the adsorption mechanism 3, which can be specifically implemented by a flexible bellows or a metal hose. Its structure of being fixed to the transmission unit 42 avoids relative displacement between the pipeline and the conveying mechanism 2.

[0100] Specifically, the transmission unit 42 establishes a mechanical linkage with the conveying mechanism 2 through the power transmission component, so that the negative pressure suction pipe 43 produces a constant speed displacement when the conveying mechanism 2 is running, and the negative pressure generated by the negative pressure suction component 41 is continuously transmitted to the connecting air pipe 33 of the adsorption mechanism 3 through the negative pressure suction pipe 43. When the conveying mechanism 2 drives the material to move, the transmission unit 42 drives the negative pressure suction pipe 43 to move synchronously, so that the relative position of the negative pressure suction pipe 43 and the connecting air pipe 33 remains constant. This dynamic matching mechanism eliminates the displacement difference between the traditional fixed negative pressure source and the mobile adsorption mechanism 3, ensuring that the material always obtains uniform adsorption force during high-speed transmission.
