Description

Technical Field

[0001] This application relates to the field of engraving technology, specifically to a high-speed engraving device for aluminum plates. Background Technology

[0002] From a processing principle perspective, engraving is a combination of drilling and milling. Engraving machines have multiple data input modes that can handle various needs with ease. Computer engraving machines are divided into two categories: laser engraving and mechanical engraving. Both of these categories are divided into high-power and low-power types. Low-power machines are only suitable for making two-color boards, architectural models, small signs, and three-dimensional crafts. Engraving jade and metal requires a power of 1500W or more. High-power engraving machines can do the same things as low-power machines and are best suited for large-scale cutting, relief carving, and engraving.

[0003] However, existing plate engraving machines generally use pressure blocks to fix the plates. This method has significant drawbacks. The pressure blocks directly contact the plate surface and apply pressure, which can easily leave indentations during engraving and even interfere with the operation of the engraving tools, affecting the accuracy and quality of the engraving and impacting the processing. Furthermore, because plates are typically large in area and mass, operators need to spend considerable time and effort lifting or moving the plates during installation, making precise fine-tuning difficult. This not only increases labor intensity but also reduces production efficiency. Therefore, these problems urgently need to be addressed. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a high-speed engraving device for aluminum plates.

[0005] This application provides a high-speed engraving device for aluminum plates, including...

[0006] The frame has a worktable on its top and sliding tables on both sides of the worktable.

[0007] The worktable is provided with an array of annular suction cups and supporting balls located in the middle of the annular suction cups;

[0008] The annular suction cup is embedded in the worktable and is used to adsorb and fix the board.

[0009] The supporting ball bearings are connected to the worktable via a limiting sleeve;

[0010] The limiting sleeve is embedded in the worktable and has a stepped hole inside for installing the supporting ball.

[0011] The stepped hole includes a main channel with a diameter matching the supporting ball and a limiting part with a relatively small diameter located at the top of the limiting sleeve;

[0012] The main channel is also equipped with a spring, and the end away from the limiting part passes through the limiting sleeve, forming an open structure;

[0013] The spring is located at the end of the support ball away from the limiting part, and is used to drive the support ball to self-reset.

[0014] Furthermore,

[0015] The two slides are connected by a gantry frame;

[0016] The gantry frame includes vertical columns mounted on the slide and a crossbeam connecting the two columns.

[0017] A carving head is movably mounted on the crossbeam for carving the board material;

[0018] A dust collection hood is installed across the two columns to collect debris.

[0019] Furthermore,

[0020] The number of dust collection hoods includes two, located on both sides of the column along the direction of movement;

[0021] The dust collection hood includes a flow channel section with a circular cross-section and a negative pressure section located near the carving head.

[0022] The negative pressure section has a rectangular cross-section and is connected to the flow channel section tangentially, for sucking the debris into the flow channel section.

[0023] Furthermore,

[0024] The end of the flow channel is connected to an external vacuum device, and a matching interface is provided on one side corresponding to the negative pressure section.

[0025] The interface is located at the top of the flow channel near the engraving head;

[0026] The negative pressure section and the flow channel section are installed at an angle, with the end closer to the interface being relatively higher.

[0027] Furthermore,

[0028] The engraving head is connected to the crossbeam via a sliding block;

[0029] The slide block is connected to the crossbeam via a first linear guide rail, and the sliding direction is parallel to the extension direction of the crossbeam.

[0030] The crossbeam is also provided with a first ball screw corresponding to the slide block, which is used to drive the slide block to slide relative to the crossbeam.

[0031] Furthermore,

[0032] The slide block and the engraving head are connected by a sliding plate;

[0033] The slide plate and the slide base are connected by a second linear guide rail, and the sliding direction is parallel to the vertical direction;

[0034] The slide block is also provided with a second ball screw corresponding to the slide plate, which is used to drive the slide plate to slide relative to the slide block.

[0035] Furthermore,

[0036] The annular suction cups are connected to an external negative pressure device via flexible hoses, and electromagnetic valves for controlling the on / off state are also provided between the suction cups and the flexible hoses.

[0037] The negative pressure device is connected to the hose via a main pipe, and a main valve for controlling the on / off state is provided between the device and the main pipe.

[0038] Furthermore,

[0039] The limiting sleeve is equipped with a photoelectric switch that is linked to the solenoid valve.

[0040] The photoelectric switch is fixedly installed on the workbench and is triggered and controls the opening and closing of the solenoid valve by the support ball.

[0041] The advantages and positive effects of this application are:

[0042] This technical solution uses supporting balls on the worktable to form rolling support with the sheet metal, facilitating sheet metal adjustment. Simultaneously, the supporting balls are spring-supported to the worktable; when the suction cup adheres to the sheet metal, the pressure on the sheet metal is much greater than the spring's supporting force, ensuring the sheet metal is firmly pressed against the worktable, thus guaranteeing installation stability. Finally, the suction cup installation method ensures the processed surface of the sheet metal remains undisturbed, effectively improving processing quality and efficiency.

Detailed Implementation

[0047] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0048] Please refer to Figure 1-3 This embodiment provides a high-speed aluminum plate engraving device, including a frame 100. A worktable 200 is provided on the top of the frame 100, and sliding slides 300 are respectively provided on both sides of the worktable 200. The worktable 200 is provided with an array of annular suction cups 210 and supporting balls 220 located in the middle of the annular suction cups 210. The annular suction cups 210 are embedded in the worktable 200 for adsorbing and fixing the plate material. The supporting balls 220 are connected to the worktable 200 by a limiting sleeve 230. The limiting sleeve 230 is embedded in the worktable 200 and has a stepped hole inside for installing the support ball 220. The stepped hole includes a main channel with a diameter matching the support ball 220 and a limiting part with a relatively small diameter located at the top of the limiting sleeve 230. A spring 231 is also provided in the main channel, and one end away from the limiting part passes through the limiting sleeve 230, forming an open structure. The spring 231 is located at the end of the support ball 220 away from the limiting part and is used to drive the support ball 220 to self-reset.

[0049] In this embodiment, a workbench 200 is provided on the top of the frame 100, and slides 300 are provided on both sides of the workbench 200; there is a certain distance between the slides 300 and the workbench 200, which facilitates the processing of the edges of the board.

[0050] In this embodiment, the top of the workbench 200 is provided with an array of annular suction cups 210, which can not only adsorb the board onto the workbench 200, but also make the force on each part of the board uniform; compared with the traditional edge pressing method, not only is the processing at the edge not restricted, but sufficient stability can also be ensured in the middle.

[0051] In this embodiment, each annular suction cup 210 is also provided with a support ball 220 in the middle; the support ball 220 is installed on the workbench 200 by a limiting sleeve 230, so that it can both support the board and retract to the bottom of the table to prevent it from affecting the fixation of the board.

[0052] In this embodiment, the worktable 200 is provided with a matching threaded hole corresponding to the limiting sleeve 230; the limiting sleeve 230 can be fully embedded in the threaded hole through the external thread; the spring 231 has one end abutting against the bottom of the threaded hole and the other end abutting against the supporting ball 220. The supporting ball 220 can not only offset part of the weight of the plate through the support of the spring, thus facilitating handling and adjustment, but also retract into the interior of the limiting sleeve 230 when the annular suction cup 210 adsorbs the plate because the elastic force is much less than the gravity.

[0053] In a preferred embodiment, the two slides 300 are connected by a gantry frame; the gantry frame includes columns 310 vertically mounted on the slides 300 and a crossbeam 320 connecting the two columns 310; an engraving head 321 is movably mounted on the crossbeam 320 for engraving the board; a dust collection hood 330 is bridging the two columns 310 for collecting debris.

[0054] In this embodiment, the gantry frame is installed across the worktable 200, and the columns 310 at both ends are respectively installed vertically on the slide table 300, thereby enabling relative movement between the crossbeam 320 and the worktable 200; the engraving head 321 is installed on the crossbeam 320, and can move accordingly by moving the crossbeam 320.

[0055] In a preferred embodiment, the number of dust collection hoods 330 includes two, located on both sides of the column 310 along the direction of movement; each dust collection hood 330 includes a flow channel portion with a circular cross-section and a negative pressure portion located near the engraving head 321; the negative pressure portion has a rectangular cross-section and is connected to the flow channel portion tangentially, for sucking the debris into the flow channel portion.

[0056] In this embodiment, the dust collection hood 330 is installed on two columns 310 at both ends. With the sliding of the columns 310, the entire workbench 200 can be cleaned.

[0057] In this embodiment, there are two dust collection hoods 330, located on both sides of the column 310 along the sliding direction and on both sides of the engraving head 321, so that the debris can be collected in real time during the engraving process to avoid the debris affecting the processing.

[0058] In a preferred embodiment, the end of the flow channel is connected to an external vacuum device, and a matching interface is provided on one side corresponding to the negative pressure part; the interface is located at the top of the flow channel near the engraving head 321; the negative pressure part and the flow channel are installed at an angle, and the end near the interface is relatively higher.

[0059] In this embodiment, one end of the flow channel is a sealed structure, and the other end is connected to an external vacuum device. With the help of the interface on one side, a negative pressure can be formed to suck in and discharge debris. At the same time, the interface is located at a relatively upper position of the flow channel, so that when debris enters the flow channel, it can also prevent it from being accidentally discharged again through the interface.

[0060] In a preferred embodiment, the engraving head 321 is connected to the crossbeam 320 via a slide block 340; the slide block 340 is connected to the crossbeam 320 via a first linear guide rail, and the sliding direction is parallel to the extension direction of the crossbeam 320; the crossbeam 320 is also provided with a first ball screw corresponding to the slide block 340, for driving the slide block 340 to slide relative to the crossbeam 320.

[0061] In this embodiment, the slide block 340 is slidably mounted on one side of the crossbeam 320 via the first linear guide rail, thereby enabling the engraving head 321 to move arbitrarily within the plane.

[0062] In a preferred embodiment, the slide block 340 and the engraving head 321 are connected by a slide plate 350; the slide plate 350 and the slide block 340 are connected by a second linear guide rail, and the sliding direction is parallel to the vertical direction; the slide block 340 is also provided with a second ball screw corresponding to the slide plate 350, for driving the slide plate 350 to slide relative to the slide block 340.

[0063] In this embodiment, the slide plate 350 is slidably mounted on the slide base 340 via the second linear guide rail, which also realizes the lifting function of the engraving head 321, so that the engraving head 321 can engrave different depths.

[0064] In a preferred embodiment, the annular suction cup 210 is connected to an external negative pressure device via a flexible hose, and a solenoid valve for controlling the on / off state is provided between the suction cup and the flexible hose; the negative pressure device is connected to the flexible hose via a main pipe, and a main valve for controlling the on / off state is provided between the negative pressure device and the main pipe.

[0065] In a preferred embodiment, the limiting sleeve 230 is provided with a photoelectric switch that is linked to the solenoid valve; the photoelectric switch is fixedly installed on the worktable 200 and is triggered and controls the opening and closing of the solenoid valve by the support ball 220.

[0066] In this embodiment, the worktable 200 is also equipped with a photoelectric switch at the bottom of the threaded hole corresponding to the support ball 220. When the support ball 220 is fully supported by the spring 231, the solenoid valve is closed, so that the annular suction cup 210 without a plate position will not work; conversely, when the support ball 220 is compressed, the solenoid valve will switch the state to generate negative pressure in the annular suction cup 210.

[0067] In this embodiment, when installing the board, the main valve is closed first, so that the board will not be subjected to the negative pressure suction of the annular suction cup 210 during the adjustment process; after the position adjustment is completed, the main valve is opened, and the annular suction cup 210 in contact with the board will generate negative pressure to fix the board on the worktable 200.

[0068] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this invention, and can also combine the above technical features in an appropriate manner.
