Description

Technical Field

[0001] This invention relates to the technical field of conveying devices, specifically an automatic conveying device for a semi-automatic laser die-cutting machine. Background Technology

[0002] Laser die-cutting machines primarily utilize the high thermal energy of lasers to ablate die-cutting plates to create deep slits. They offer advantages such as straight slits, consistent slit width, low cost, and high efficiency, making them the best alternative to traditional die-cutting plate manufacturing. They are an important piece of equipment for post-printing packaging processing and are mainly used for die-cutting, creasing, and hot stamping operations on cardboard, corrugated cardboard, self-adhesive labels, EVA, double-sided adhesives, electronic and mobile phone pads, etc.

[0003] However, in the process of conveying flexible or thin materials, in order to ensure the stability of material conveying, guide plates, pressure rollers 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 conveying stability.

[0004] On the one hand, the clamping device suffers from uneven distribution of clamping force, mainly due to insufficient rigidity or unreasonable arrangement of the pressure rollers or plates. This can easily cause the material to bulge or slip, failing to adhere tightly to the conveying surface and resulting in positioning errors. On the other hand, the support width of the guide structure is too narrow, providing insufficient edge constraint for flexible materials. Especially during high-speed conveying, the material edges are prone to swaying, increasing cutting errors. Furthermore, when conveying long materials, the lack of a rigid support plate or roller underneath causes the material to sag under its own weight, disrupting its parallelism with the laser focal plane and affecting cutting quality. Even worse, the use of a single-point or narrow-surface clamping upper pressing structure may cause local bending or stress concentration in the material, resulting in wrinkles.

[0005] These structural problems, when combined, have become key obstacles restricting the improvement of die-cutting accuracy and the stable operation of equipment. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automatic conveying device for a semi-automatic laser die-cutting machine.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] This invention provides an automatic conveying device for a semi-automatic laser die-cutting machine, comprising:

Detailed Implementation

[0054] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0055] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed 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] The die-cutting mechanism 1 and the conveying mechanism 2 located at the lower end of the die-cutting mechanism 1, wherein the conveying mechanism 2 reciprocates to realize bidirectional feeding and unloading;

[0058] Both sides of the conveyor mechanism 2 are both loading and unloading areas. For example, when the left side of the conveyor mechanism 2 is preparing to load materials, the right side of the conveyor mechanism 2 has already finished processing the materials and is ready to unload them. Then, when the left side of the conveyor mechanism 2 finishes processing the materials and is ready to unload them, the right side of the conveyor mechanism 2 is ready to load them. This back-and-forth operation can prevent the negative pressure suction tube 43 from getting tangled and can improve work efficiency. In use, loading robots or other loading fixtures can be installed on both sides of the conveyor mechanism 2.

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

[0060] The adsorption mechanism 3 includes a main body unit 31, an adsorption component 32, a connecting air pipe 33, and a shielding unit 34. The adsorption component 32 is arranged in several groups and is arranged perpendicular to the transmission direction of the conveying mechanism 2. The several groups of adsorption components 32 are connected to each other through the connecting air pipe 33. The main body unit 31 has a placement slot 311 for placing the shielding unit 34 at the position corresponding to each group of adsorption components 32. After the shielding unit 34 is placed inside the placement slot 311, it will shield the air intake unit 323 at the upper end of the adsorption component 32.

[0061] A negative pressure suction mechanism 4 is also provided on the outside of the conveying mechanism 2. The negative pressure suction mechanism 4 is provided with a negative pressure suction tube 43 corresponding to each of the connecting air pipes 33, and the negative pressure suction tube 43 moves synchronously with the connecting air pipe 33.

[0062] Among them, the adsorption mechanism 3 arranged in an array forms a continuous adsorption area with a grid layout. The connecting air pipe 33 refers to a flexible pipe that runs through adjacent adsorption components 32, such as a polyurethane hose, to balance the negative pressure value of each adsorption unit 321. The shielding unit 34 includes a modular sealing block that can be embedded in the placement slot 311. It can be magnetically fixed or snap-fit ​​structure to selectively close specific adsorption areas. The synchronously moving negative pressure suction pipe 43 refers to a telescopic pipe that is linked with the conveying mechanism 2, such as a corrugated pipe with track sliding connection, to ensure that the adsorption system matches the conveying position in real time.

[0063] Specifically, when the conveying mechanism 2 is started, it drives the adsorption component 32 to move synchronously. 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 stick tightly to the conveying surface. For areas that need to be avoided for die-cutting, the operator embeds the shielding unit 34 into the corresponding placement slot 311 to seal the air intake of the adsorption component 32 at that location, avoiding waste of negative pressure and preventing local deformation of the material. After the shielding unit 34 is installed, its support structure automatically adjusts its height to maintain the flatness of the conveying surface. The negative pressure suction pipe 43 extends and retracts synchronously with the displacement of the conveying mechanism 2, eliminating the pipe twisting caused by the traditional fixed interface and ensuring continuous and stable adsorption force.

[0064] Furthermore, such as Figures 4-8 As shown, the adsorption component 32 includes an adsorption unit 321, an air intake channel 322, and an air intake unit 323. Several sets of adsorption units 321 are integrally formed. The air intake channel 322 is disposed at the lower end of the adsorption unit 321 and is interconnected with the connecting air pipe 33. The air intake unit 323 is disposed at the upper end of the air intake channel 322 and is connected to the air intake channel 322.

[0065] The adsorption unit 321 is a rigid structure integrally formed by a mold, which can be achieved by aluminum alloy extrusion molding. It forms a continuous airflow channel network inside to eliminate gap errors caused by split assembly. The suction channel 322 is an internal cavity structure extending along the length of the adsorption unit 321. It can be formed by CNC machining to form a through 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 is an airflow control module embedded in the top of the adsorption unit 321. It can be achieved by a copper suction nozzle assembly with a sealing ring. It is connected to the suction channel 322 through a vertical through hole, so that the negative pressure is directly applied to the material surface.

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

[0067] Furthermore, such as Figures 9-12As shown, the suction unit 323 includes a mounting block 3231 and a suction pipe 3232 disposed inside the mounting block 3231. The lower end of the suction pipe 3232 extends out of the mounting block 3231 and into the interior of the suction channel 322.

[0068] The adsorption unit 321 has a through groove 312 at a position corresponding to the mounting block 3231, which cooperates with the mounting block 3231.

[0069] The mounting block 3231 is a rigid structural component used to support the suction pipe 3232. It can be made of aluminum alloy or engineering plastic. It has through holes inside for fixing the suction pipe 3232. The rigidity of the mounting block 3231 can prevent the suction pipe 3232 from shifting under negative pressure and ensure that it is aligned with the axis of the suction channel 322.

[0070] The suction pipe 3232 refers to the airflow transmission pipe embedded inside the mounting block 3231. Specifically, it can be a stainless steel pipe or a rigid plastic pipe. Its lower end extends into the suction channel 322 to form an embedded connection. The extension length of the suction pipe 3232 can be 5-10 mm. By physically limiting it, the contact area with the suction channel 322 is increased, reducing the risk of airflow leakage.

[0071] Specifically, the mounting block 3231 is machined to match the external dimensions of the through groove 312 of the adsorption unit 321. When the mounting block 3231 is assembled into the through groove 312 of the adsorption unit 321, the lower end of the suction pipe 3232 is precisely inserted into the inside of the suction channel 322, forming a double sealing structure. Under negative pressure, the contact surface between the suction pipe 3232 and the suction channel 322 generates a self-tightening effect due to the air pressure difference, further enhancing the sealing performance. As a result, the airflow path inside the adsorption assembly 32 is strictly limited, avoiding negative pressure loss caused by connection gaps and ensuring that the air intake of each adsorption unit 321 is evenly distributed.

[0072] The sidewall of the through groove 312 contacts the side of the mounting block 3231 to form a physical limit, restricting the horizontal displacement of the mounting block 3231. The bottom surface of the through groove 312 contacts the bottom of the mounting block 3231. During assembly, the mounting block 3231 is embedded along the axial direction of the through groove 312, and the suction pipe 3232 is inserted into the suction channel 322 synchronously with the mounting block 3231. The geometric accuracy of the through groove 312 is controlled within ±0.05 mm to ensure that the axis of the mounting block 3231 coincides with that of the suction channel 322 after it is embedded, thus avoiding misalignment at the connection between the suction pipe 3232 and the suction channel 322.

[0073] Furthermore, such as Figures 5-10As shown, the adsorption unit 321 is also provided with an installation groove 313 at the position corresponding to the lower end of the installation block 3231, and the installation groove 313 is provided with multiple levels of support units 5.

[0074] The multi-level support unit 5 includes an integrally formed lower support part 51, a transition part 52, and an upper support part 53.

[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 recess is left between the upper surface of the mounting block 3231 and the upper surface of the adsorption unit 321.

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

[0078] Specifically, the mounting groove 313 is located directly below the core force-bearing area of ​​the mounting block 3231 at the bottom of the adsorption unit 321. The multi-level support unit 5 is embedded in the mounting groove 313 and contacts the mounting block 3231. When the mounting block 3231 needs to be flush with the surface of the adsorption unit 321, the upper support surface of the multi-level support unit 5 is selected as the support reference. When a recess needs to be formed to accommodate the shielding unit 34, the multi-level support unit 5 switches to the lower support surface, causing the mounting block 3231 to drop to a preset height. The switching of the support level is achieved by adjusting the contact position between the multi-level 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 section 51 refers to the load-bearing section located at the bottom of the support structure, which can be implemented using a rectangular block structure. It is used to bear the load of the mounting block 3231 in the low position. The transition section 52 refers to the intermediate transition area connecting the lower support section 51 and the upper support section 53. It can be implemented using a sloping or curved surface structure. It is used to guide the stress transfer when the support position is switched. The upper support section 53 refers to the load-bearing section located at the top of the support structure. It can be implemented using a platform-like structure. It is used to maintain the planar consistency between the mounting block 3231 and the adsorption unit 321 in the high position. The recessed section refers to the cavity area formed after the mounting block 3231 sinks down. It is used to provide a space for the baffle plate 342.

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

[0081] Furthermore, such as Figures 9-11 As shown, the multi-level support unit 5 also includes at least one set of connecting rod units 54, which are integrally formed with the lower support part 51, the transition part 52 and the upper support part 53.

[0082] The linkage unit 54 includes a linkage portion 541 and an arc-shaped portion 542 connected to the linkage portion 541;

[0083] The end of the multi-level support unit 5 away from the placement groove 311 is disposed inside the mounting groove 313 by a buffer spring 543.

[0084] Among them, the connecting rod unit 54 refers to the component that rigidly connects the lower support part 51, the transition part 52 and the upper support part 53. Specifically, it can be made of metal material by integral casting or injection molding. It is used to enhance the overall structural strength of the multi-level support unit 5 and prevent misalignment of each support part when under stress. The arc-shaped part 542 refers to the curved structure connected to the end of the connecting rod part 541. Specifically, it can be made of elastic material or thin-walled structure. When the blocking block 341 is squeezed, it absorbs pressure through elastic deformation and provides buffer space for the position switching of the multi-level support unit 5. The buffer spring 543 refers to the elastic element set in the mounting groove 313. Specifically, it can be made of helical spring or disc spring. It is used to provide a restoring force after the multi-level support unit 5 switches positions, so that it returns 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 part 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-shaped part 542, forcing the linkage unit 54 to drive the multi-stage support unit 5 to move away from the placement groove 311. At this time, the lower support part 51 contacts the mounting block 3231, and the mounting block 3231 sinks to form a recess. During this process, the arc-shaped part 542 offsets the impact force through elastic deformation, the linkage part 541 keeps the support parts moving synchronously, and the buffer spring 543 is compressed to store elastic potential energy. When the blocking block 341 is removed, the buffer spring 543 releases its potential energy and pushes the multi-stage support unit 5 back to its initial position.

[0086] Furthermore, such as Figures 5-8 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 slot 311, the upper support 53 is used to support the mounting block 3231;

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

[0089] The shielding block 341 is a rigid component used to trigger the switching of the support structure. It can be made of aluminum alloy or engineering plastic block. Its bottom shape forms an interference fit with the placement groove 311. The component drives the multi-level support unit 5 to generate displacement through mechanical contact. The shielding plate 342 is a planar covering that is rigidly connected to the shielding block 341. It can be made of a thin plate with the same material as the surface of the adsorption unit 321. Its thickness is equal to the depth of the recess. It is used to fill the gap formed by the sinking of the mounting block 3231. The multi-level support unit 5 is an elastic structure with a stepped support surface. It can be made of spring steel sheet stamping. The radius of curvature of its arc part 542 matches the edge of the shielding block 341. 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 part 53 of the multi-stage support unit 5 lifts the mounting block 3231 to a state flush with the adsorption unit 321. When the blocking block 341 is inserted into the placement slot 311, its sidewall contacts and presses the arc-shaped part 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 part 51 replaces the upper support part 53 to support the mounting block 3231, causing the mounting block 3231 to sink and form a recess. The blocking plate 342 fixed to the blocking block 341 moves synchronously to the top of the recess, and its plate thickness just fills the recessed space, making the overall adsorption surface flat again. This process achieves the synchronous conversion between the support state and the blocking action through pure mechanical linkage, without the need for an additional power device.

[0091] Furthermore, such as Figure 5 As shown, an adsorption member 6 is provided inside the placement groove 311, and the blocking block 341 is detachably disposed inside the placement groove 311 via the adsorption member 6.

[0092] The upper end of the shielding block 341 is provided with at least one set of grooves 3411.

[0093] The adsorption component 6 refers to the adsorption structure set in the placement groove 311 for fixing the shielding block 341. Specifically, it can be implemented by using a permanent magnet or an electromagnetic adsorption component 32, which maintains the positional stability of the shielding block 341 in a vibration environment through adsorption force.

[0094] The groove 3411 refers to the recessed structure formed on the upper end of the shielding block 341. Specifically, it can be implemented by using a U-shaped groove or a rectangular groove. The shielding block 341 can be disassembled by lever by leaving space for inserting tools.

[0095] Specifically, the blocking block 341 is magnetically attracted to the placement groove 311 by the magnetic force of the adsorption component 6, maintaining a fixed state during the operation of the die-cutting machine to prevent displacement due to vibration. When maintenance is required, the operator inserts a tool into the groove 3411 and uses the torque generated by prying the tool to overcome the adsorption force, causing the blocking block 341 to detach from the placement groove 311. During this process, the depth and width of the groove 3411 are designed to accommodate standard tool sizes, such as screwdrivers or special pry bars, ensuring convenient disassembly. The contact surface between the blocking block 341 and the placement groove 311 is machined using a flat surface process, ensuring a uniform distribution of the adsorption force and preventing deformation caused by localized stress concentration.

[0096] Furthermore, such as Figures 1-3 As shown, the negative pressure suction mechanism 4 includes a negative pressure suction component 41, a transmission unit 42 disposed on one side of the negative pressure suction component 41 and working synchronously with the conveying mechanism 2, and several sets of negative pressure suction tubes 43 fixedly disposed on the transmission unit 42.

[0097] Among them, the negative pressure suction component 41 refers to the device used to generate negative pressure, which can be achieved by a vacuum pump or a centrifugal fan. Its function is to provide a stable negative pressure source for the adsorption mechanism 3.

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

[0099] The negative pressure suction tube 43 refers to the pipe connecting the negative pressure suction component 41 and the adsorption mechanism 3. Specifically, it can be implemented using a flexible corrugated pipe or a metal hose. Its structure, which is fixed to the transmission unit 42, avoids relative displacement between the pipe 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 tube 43 generates a constant speed displacement when the conveying mechanism 2 is running. 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 tube 43. When the conveying mechanism 2 moves the material, the transmission unit 42 drives the negative pressure suction tube 43 to move synchronously, so that the relative position of the negative pressure suction tube 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 moving adsorption mechanism 3, ensuring that the material always obtains uniform adsorption force during high-speed conveying.
