Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to an adsorption edge positioning device based on a five-axis linkage printing device and a five-axis printing device. Background Technology

[0002] Five-axis 3D printing is one of the latest innovations in additive manufacturing. Compared to traditional 3D printers, which move in three dimensions along three different spatial axes (X, Y, and z), it adds two additional rotational axes. This technology is not limited by planar layer orientations, allowing for the formation of more complex parts without the need for support materials, thus increasing strength and reducing printing time. Because the tool head of a five-axis 3D printer can print on multiple planes, it can create parts with complex geometries without support.

[0003] To control the product loading and positioning accuracy, five-axis linkage printing equipment usually designs a positioning mechanism around the adsorption component. In existing five-axis linkage printing equipment, the adsorption mechanism and the positioning mechanism are mostly integrated into one design. This structure will cause interference with the Z-axis printing needle position at certain angles during five-axis linkage printing.

[0004] A Chinese patent document, CN219505160U, discloses a "vacuum adsorption positioning device." This device includes a workpiece adsorption clamp, an adsorption tank clamp, and a base. A vacuum pump is connected below the adsorption tank clamp, and the adsorption tank clamp and the workpiece adsorption clamp are arranged sequentially from bottom to top above the base. The vacuum adsorption positioning device is designed to closely fit different curved surfaces of the workpiece adsorption clamps with the workpieces to be processed, maintaining a high vacuum state inside both the workpiece adsorption clamp and the adsorption tank clamp. This ensures the workpiece is firmly adsorbed within the workpiece adsorption clamp for cutting operations, preventing displacement and loosening. However, this integrated positioning and adsorption device limits its usability in certain working environments. In five-axis simultaneous printing, positional interference issues still exist at certain angles, making it unsuitable for solving the loading and positioning problems in five-axis simultaneous printing. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an adsorption edge positioning device and a five-axis printing device based on a five-axis linkage printing equipment, so as to solve the problem that the adsorption mechanism and positioning mechanism in the existing five-axis linkage printing equipment are mostly integrated, and there will be positional interference at certain angles during printing, which makes it unsuitable for five-axis linkage feeding and positioning.

[0006] To achieve the above-mentioned and other related objectives, this utility model is implemented through the following technical solutions.

[0007] This utility model provides an adsorption edge positioning device, including a separate edge positioning mechanism and an adsorption mechanism. The adsorption mechanism is used to adsorb a substrate, and the edge positioning mechanism is used to position the substrate. The edge positioning mechanism includes an edge positioning component and a driving component, and the driving component is used to drive the edge positioning component to move closer to or away from the adsorption mechanism.

[0008] When applied to a five-axis simultaneous printing machine, the adsorption and edge positioning device of this invention features a separate design for the adsorption mechanism and the edge positioning mechanism. When positioning is required, a drive assembly moves the edge positioning component closer to the adsorption mechanism; after positioning is complete, the drive assembly moves the edge positioning component away from the adsorption mechanism, preventing interference with the Z-axis printing needle position during five-axis simultaneous printing operation. The edge positioning component can be customized according to the specific shape of the product, accommodating various product sizes; the adjustable stroke of the drive assembly allows for adjustable positioning of the substrate.

[0009] Preferably, the edge positioning member has a limiting portion adapted to the shape of the substrate, and the limiting portion contacts at least two edges of the substrate when the edge positioning member approaches the adsorption mechanism.

[0010] In the above technical solution of this application, by limiting the limiting part to contact at least two sides of the substrate, positional displacement is avoided, and a better limiting effect can be produced.

[0011] Preferably, the limiting portion makes point contact with the substrate when it approaches the adsorption mechanism.

[0012] In the above technical solution of this application, the contact area between the edge positioning mechanism and the product is greatly reduced by the point contact between the limiting part and the substrate, thereby reducing friction caused during contact and reducing contact damage to the product.

[0013] Preferably, the contact surface between the limiting part and the substrate is formed with an arc-shaped protrusion, thereby forming a point contact between the limiting part and the substrate.

[0014] Preferably, the edge positioning mechanism and the adsorption mechanism are not parallel and not perpendicular.

[0015] Preferably, the movement direction of the edge positioning member is staggered with the contact surface between the limiting part and the substrate.

[0016] In the above technical solution of this application, by controlling the edge positioning mechanism and the adsorption mechanism to be set in a non-parallel and non-perpendicular manner, preferably the movement direction of the edge positioning member and the contact surface between the limiting part and the substrate are staggered rather than parallel, it is possible that when the driving component drives the edge positioning member away from the adsorption mechanism, the edge positioning member will immediately separate from the substrate, preventing friction with the product and further reducing contact damage to the product.

[0017] Preferably, the adsorption mechanism includes an adsorption stage and a vacuum adsorption disk integrally formed with the adsorption stage. The vacuum adsorption disk is adapted to the shape of the substrate. The vacuum adsorption disk has negative pressure vents and adsorption channels. The negative pressure vents penetrate the adsorption stage and the vacuum adsorption disk. The negative pressure vents are used to connect an external vacuum generator.

[0018] In the above-mentioned technical solution of this application, by using a vacuum adsorption cup to form a relative vacuum area based on negative pressure, the substrate is pressed tightly onto the suction cup by atmospheric pressure. On the one hand, this ensures the stability and efficiency of the handling process, and on the other hand, it does not damage the surface of the adsorbed object. In addition, it can also be applied to the adsorption of substrates of different shapes, making it more widely applicable.

[0019] Preferably, the edge positioning mechanism further includes a bracket, and the driving component includes a slide rail, a slider, and a driving member for driving the slider to move along the slide rail, all mounted on the bracket. The edge positioning member is fixedly connected to the slider.

[0020] More preferably, the driving component is a telescopic cylinder, which includes a cylinder body and a telescopic rod. The cylinder body is fixedly connected to the bracket, and the telescopic rod is fixedly connected to the slider.

[0021] In the above technical solution of this application, the distance the side positioning member moves when it approaches or moves away from the adsorption mechanism can be controlled by controlling the stroke of the telescopic cylinder.

[0022] This invention also provides a five-axis printing device including the above-mentioned adsorption and edge positioning device.

[0023] Preferably, the five-axis printing equipment further includes a feeding mechanism for receiving a substrate conveyed from upstream, and the adsorption edge positioning device for positioning the substrate.

[0024] As described above, the adsorption edge positioning device and five-axis printing equipment of this utility model have the following beneficial effects:

[0025] (1) By designing the adsorption mechanism and the edge positioning mechanism as separate units, when positioning is required, the driving component is used to drive the edge positioning component to approach the adsorption mechanism; after positioning is completed, the driving component is used to drive the edge positioning component to move away from the adsorption mechanism, so that it will not interfere with the Z-axis printing needle position when the five-axis linkage printing equipment is working.

[0026] (2) The edge positioning component can be set according to the specific shape of the product, and can be compatible with various product sizes and positioning position adjustments; the motion stroke of the drive component is adjustable, so that the positioning position of the substrate can be adjusted;

[0027] (3) By making point contact with the substrate through the limiting part, the contact area between the edge positioning mechanism and the product is greatly reduced, the friction caused during contact is reduced, and the contact damage to the product is reduced.

[0028] (4) By controlling the movement direction of the edge positioning member and the contact surface between the limiting part and the substrate to be staggered instead of parallel, when the driving component drives the edge positioning member away from the adsorption mechanism, the edge positioning member can be immediately separated from the substrate to prevent friction with the product when exiting, and further reduce contact damage to the product.

[0037] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0038] Please see Figures 1 to 7It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0039] like Figure 1 As shown, this utility model provides an adsorption edge positioning device, including a separately configured edge positioning mechanism 1 and an adsorption mechanism 2. The edge positioning mechanism and the adsorption mechanism are not parallel or perpendicular. The adsorption mechanism is used to adsorb a substrate, and the edge positioning mechanism is used to position the substrate. Figure 2 As shown, the edge positioning mechanism includes an edge positioning component 11, a driving assembly, and a bracket 13. The driving assembly is used to drive the edge positioning component to move closer to or away from the adsorption mechanism.

[0040] like Figure 3 and Figure 5 As shown, the edge positioning member has a limiting portion 12 adapted to the shape of the substrate, and the contact surface between the limiting portion and the substrate has an arc-shaped protrusion 121, such as... Figure 4 As shown, the arc-shaped protrusion allows the limiting part to make point contact with the substrate when it is close to the adsorption mechanism; the limiting part makes contact with the two sides of the substrate when the edge positioning member is close to the adsorption mechanism.

[0041] Combination Figure 3 and Figure 4 The movement direction of the edge positioning member is staggered with the contact surface between the limiting part and the substrate, and the angle between the movement direction of the edge positioning member and the contact surface between the limiting part and the substrate is 45°. By controlling the movement direction of the edge positioning member to be staggered with the contact surface between the limiting part and the substrate, instead of being parallel, the edge positioning member can be immediately separated from the substrate when the driving component drives the edge positioning member away from the adsorption mechanism, preventing friction with the product during withdrawal and further reducing contact damage to the product.

[0042] Combination Figure 2 , Figure 3 and Figure 4The driving assembly includes a slide rail 131 mounted on a bracket, a slider 132, and a driving component for driving the slider to move along the slide rail. The edge positioning component is fixedly connected to the slider. The driving component is a telescopic cylinder, which includes a cylinder body and a telescopic rod. The cylinder body is fixedly connected to the bracket, and the telescopic rod is fixedly connected to the slider. The distance the edge positioning component moves closer to or further away from the adsorption mechanism can be controlled by controlling the stroke of the telescopic cylinder. Figure 2 , Figure 6 and Figure 7 The adsorption mechanism includes an adsorption stage 21 and a vacuum adsorption disk 22 integrally formed with the adsorption stage. The vacuum adsorption disk is adapted to the shape of the substrate. The vacuum adsorption disk has negative pressure vents 221 and adsorption channels 222. The negative pressure vents penetrate the adsorption stage and the vacuum adsorption disk. The negative pressure vents are used to connect an external vacuum generator.

[0043] This application embodiment also provides a working principle for the above-mentioned adsorption edge positioning device to be used in a five-axis printing equipment for positioning the feeding mechanism:

[0044] When the feeding mechanism receives the substrate from the upstream, the vacuum adsorption plate 22 forms a relative vacuum area based on negative pressure. Atmospheric pressure is used to press the substrate tightly onto the vacuum adsorption plate. The extension rod of the telescopic cylinder extends to drive the slider 132 to move along the slide rail 131, thereby driving the edge positioning member 11 to move closer to the adsorption mechanism 2. The limiting part (12) is positioned by point contact between the three arc-shaped protrusions 121 on the contact surface between the limiting part and the substrate and the substrate. At this time, the state of the adsorption edge positioning device is as follows: Figure 2 and Figure 4 As shown.

[0045] After positioning is completed, the telescopic cylinder retracts, driving the slider 132 to move along the slide rail 131, thereby causing the edge positioning member 11 to move away from the adsorption mechanism 2. Since the movement direction of the edge positioning member is staggered with the contact surface between the limiting part and the substrate, rather than parallel, the edge positioning member immediately separates from the substrate when it moves away from the adsorption mechanism, avoiding friction with the product and reducing contact damage. At this time, the adsorption edge positioning device is in the following state: Figure 1 and Figure 3 As shown, it will not interfere with the Z-axis printing needle position when the five-axis linkage printing equipment is working.

[0046] In summary, this invention features a separate design for the adsorption mechanism and the edge positioning mechanism. When positioning is required, a drive assembly moves the edge positioning component closer to the adsorption mechanism; after positioning is complete, the drive assembly moves the edge positioning component away from the adsorption mechanism, thus preventing interference with the Z-axis printing needle position during five-axis linkage printing. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
