Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a rotary printing platform. Background Technology

[0002] 3D resin printing is an additive manufacturing process that uses photosensitive resin to build three-dimensional objects layer by layer through photocuring technology. It uses an ultraviolet light source to cure resin layer by layer according to CAD-defined sample slices. After the printing platform descends, printing continues. However, during the printing process, a large amount of resin residue often remains on the finished product, requiring cleaning with alcohol or other cleaning solutions. Traditionally, this involves removing the finished product from the printing platform for cleaning, which is not only cumbersome but also prone to damaging the product. While there are devices that can directly place the entire printing platform along with the finished product into a cleaning device, the finished product often has multiple pores inside, where resin residue easily accumulates, increasing the difficulty and effectiveness of cleaning. While shaking is often used to dislodge the liquid, this can affect the stability of the printing platform and thus printing accuracy. Utility Model Content

[0029] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0030] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0032] An embodiment of this utility model provides a rotary printing platform, such as... Figure 1-6 As shown, it includes:

[0033] Printing platform component 101;

[0034] The rotating device 201 is used to drive the printing platform assembly 101 to rotate. The rotating device 201 includes a first fixed base 202 and a driving structure 203 disposed on the first fixed base 202 for driving the printing platform assembly 101 to rotate.

[0035] A limiting device 204 is disposed on the first fixed base 202, and the limiting device 204 is used to limit the rotation angle of the printing platform assembly 101.

[0036] The limiting device 204 has a limiting state and a releasing state. When the printing platform assembly 101 rotates to the preset position, the limiting device 204 can restrict the rotation of the printing platform assembly 101 and enter the limiting state; when the driving structure 203 drives the printing platform assembly 101 to rotate, the limiting device 204 releases the limiting state from the printing platform assembly 101.

[0037] The rotating device 201 drives the printing platform assembly 101 to rotate, enabling it to rotate during the cleaning process. This facilitates the emptying of accumulated liquid from the workpiece holes, improving cleaning efficiency and effectiveness. Because the rotating device 201 allows the printing platform assembly 101 to rotate, the limiting device 204 securely fixes it to one side of the first fixed base 202 during printing. This effectively prevents the printing platform assembly 101 from rotating during printing or experiencing poor platform stability due to vibration or external forces, thus ensuring printing accuracy and quality. Specifically, one preset position is the location of the printing platform assembly 101 during printing; in this embodiment, this preset position is horizontal. Furthermore, the limiting device 204 can also limit the rotation angle of the printing platform assembly 101 during liquid cleaning, preventing excessive rotation. The limiting device 204 has a limiting state and a releasing limiting state. It can limit the movement by means of snapping, abutting, or inserting. It can release the limiting state when rotation is required, allowing the platform to rotate freely. When fixing is required, it enters the limiting state to ensure platform stability and make operation flexible and convenient.

[0038] In some embodiments, such as Figure 1-4 As shown, the limiting device 204 includes a limiting block 205 that can rotate with the printing platform assembly 101 and a limiting seat 206 that cooperates with the limiting block 205. The limiting seat 206 is used to fix the limiting block 205.

[0039] When the limit block 205 abuts against the limit seat 206, the limit device 204 enters the limit state, thereby limiting the rotation of the printing platform component 101; when the limit block 205 separates from the limit seat 206, the limit device 204 enters the release state.

[0040] When the printing platform assembly 101 is in a preset position set by those skilled in the art, the limiting block 205 and the limiting seat 206 abut against each other to limit the rotation of the printing platform assembly 101, thereby fixing the printing platform assembly 101 in the preset position, ensuring stability during printing, and preventing print quality from being affected by vibration. The limiting block 205 and the limiting seat 206 offer high flexibility in their installation positions; they can be placed in different positions while ensuring firmness, and multiple blocks can be used for joint fixation to further enhance stability. Specifically, for example... Figure 1-2 In the illustrated embodiment, when the driving structure 203 drives the limiting block 205 to rotate to one side of the limiting seat 206, it will cause a stall. The limiting block 205 abuts against the limiting seat 206 to limit the rotation angle of the printing platform assembly 101, thus firmly fixing the printing platform assembly 101 in a preset position. Figure 3-4 In the illustrated embodiment, the limiting block 205 and the limiting seat 206 fix the printing platform assembly 101 by adsorption and limiting. Furthermore, the limiting seat 206 can also be fixed by the limiting block 205 being inserted into the limiting seat 206 and abutting against it.

[0041] Furthermore, such as Figure 5-6 As shown, the limiting seat 206 includes a first limiting part 210 and a second limiting part 211 that can abut against the limiting block 205. The first limiting part 210 and the second limiting part 211 are used to limit the rotation angle of the printing platform assembly 101.

[0042] The first limiting part 210 and the second limiting part 211 are preset at the required angles and can cooperate with the limiting block 205 to limit the rotation angle of the printing platform assembly 101, ensuring that the platform rotates within a specific angle range; such as Figure 5-6 In this embodiment, the first limiting part 210 and the second limiting part 211 are arranged vertically and horizontally on one side to realize large-angle rotation of the printing platform assembly 101.

[0043] Furthermore, such as Figure 3-4 As shown, a positioning structure 208 is provided on one side of the limiting block 205 or the limiting seat 206. The positioning structure 208 is used to position the rotational position of the printing platform assembly 101.

[0044] The positioning structure 208 is designed to allow the printing platform assembly 101 to rotate to the position of the positioning structure 208, thereby driving the limiting device 204 into a limiting state; or to stop the drive structure 203 from driving when it rotates to the position of the positioning structure 208. The positioning structure 208 can be a sensor, switch, or other similar structure.

[0045] In some embodiments, such as Figure 3-4 The limiting block 205 and the limiting seat 206 are provided with an electromagnetic part 207, which can drive the limiting seat 206 to attract or disconnect from the limiting block 205.

[0046] The electromagnetic control of the electromagnetic unit 207 enables the rapid fixing and de-fixing of the limiting block 205 and the limiting seat 206. The adsorbed structure is a magnetic metal such as iron, cobalt, or nickel. Electromagnetic adsorption simplifies the operation of entering the limiting state and provides a rapid response, improving the fixing efficiency and flexibility of the printing platform assembly 101. Simultaneously, electromagnetic adsorption provides a stable fixing force, ensuring the stability of the printing process, avoiding problems of insecure fixing due to mechanical wear, and extending the service life of the equipment.

[0047] In some embodiments, such as Figure 3-4 As shown, the printing platform assembly 101 includes a second mounting base 102 connected to the drive structure 203 and a printing platform body 103 disposed below the second mounting base 102.

[0048] The second mounting bracket 102 can stably connect the drive structure 203 and the printing platform body 103, providing good support for the printing platform body 103.

[0049] Furthermore, such as Figure 2-3 As shown, the second fixing seat 102 has an anti-overflow groove 104 on the side facing the printing platform body 103, and the printing platform body 103 is set in the anti-overflow groove 104.

[0050] The printing platform body 103 is set inside the overflow tank 104, so that when the device rotates, the liquid can flow into the overflow tank 104 along the printing platform body 103, effectively preventing the resin from overflowing onto other structures during rotation and avoiding resin contamination of the equipment.

[0051] Furthermore, such as Figure 3 As shown, the bottom of the printing platform body 103 gradually slopes towards the anti-overflow groove 104 from the outside to the inside.

[0052] The sloping bottom guides the resin to flow into the overflow tank 104, further preventing resin spillage.

[0053] In some embodiments, such as Figure 3-4As shown, the drive structure 203 includes a drive motor 212 mounted on the first fixed base 202 and a rotating part 213 connected to the printing platform assembly 101. The drive motor 212 is used to drive the rotating part 213 to rotate, thereby driving the printing platform assembly 101 to rotate.

[0054] The drive motor 212 can achieve precise angle control of the printing platform component 101 by rotating and keeping the rotation constant 213, which can meet the needs of different operations and improve the flexibility and practicality of the equipment. Furthermore, the drive motor 212 can be a servo motor, stepper motor, geared motor or servo motor.

[0055] Furthermore, such as Figure 4 As shown, the limiting block 205 is disposed on the printing platform assembly 101 or the rotating part 213.

[0056] The limiting block 205, whether mounted on the printing platform assembly 101 or the rotating part 213, can limit the rotation of the printing platform assembly 101 by being fixed to the limiting seat 206; for example Figure 1-2 In the illustrated embodiment, the limiting block 205 is disposed on the rotating part 213 to facilitate cooperation with the limiting seat 206. Figure 3-4 In the embodiment shown, the electromagnetic part 207 is disposed on one side of the limiting seat 206, and the limiting block 205 is disposed on the rotating part 213. The limiting block 205 cooperates with the limiting seat 206 through electromagnetic adsorption, which can firmly fix the printing platform assembly 101 when it needs to be fixed, ensuring the stability of the printing process. At the same time, the electromagnetic adsorption method of the limiting seat 206 makes it easy to quickly release the fixing from the limiting block 205, so that the printing platform assembly 101 can rotate smoothly.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
