Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a guide rail module and a three-dimensional molding device. Background Art

[0002] In a light-curing 3D printer, the material tank contains the printing resin, and the guide rail module drives the printing platform to move to a thickness of one layer of the model between the release film of the material tank. The light source irradiates the resin from one side of the material tank, so that the resin solidifies between the printing platform and the release film to form a layer of the model. Then the guide rail module drives the printing platform to rise, and the formed model will be separated from the release film. The resin fills the space between the formed model and the release film, and then repeatedly exposes and stacks layer by layer to achieve three-dimensional molding.

[0003] Whether the formed model is completely released from the mold is the key to the success of printing. Usually, a sensor is set on the cantilever of the printing platform. The sensor is connected to the base of the 3D printer through a cable. The sensor detects the tension on the cantilever and transmits it to the main controller, thereby realizing the monitoring of the printing process. In the prior art, the cable is a single-form cable. For example, the cable is a single non-spring cable. The lifting of the printing platform will cause irregular accumulation of the cable, and the cable is easy to be entangled and knotted, causing the movement of the printing platform to jam. Or the cable is a single spring cable. The spring cable is heavy and the cable elasticity is too large, resulting in a heavy burden on the lifting of the printing platform, and the increase in the total length of the cable will lead to unstable signal transmission. Utility Model Content

[0004] In view of this, in order to solve at least one of the above technical problems, the utility model provides a guide rail module and a three-dimensional forming device.

[0005] In order to achieve the above purpose, the utility model mainly provides the following technical solutions:

[0006] On the one hand, the utility model provides a guide rail module for a three-dimensional forming device, the guide rail module comprising:

[0007] Slide rails;

[0009] The cable is electrically connected to at least the functional electrical element, the cable is used to transmit the detection signal of the functional electrical element, and the cable includes an elastic area and a non-elastic area.

[0010] On the other hand, the utility model further provides a three-dimensional forming device, characterized in that it includes any one of the guide rail modules described above.

[0011] The utility model proposes a guide rail module and a three-dimensional forming device, which mainly realizes that the cables are not easy to pile up and knot by setting the cables connecting the functional electrical components as a combination of spring cables and non-spring cables, and avoids bending damage caused by excessive cable tension, and avoids signal instability caused by excessive cable length. In the prior art, the cable between the induction component and the base of the 3D printer is a single-form cable. For example, if the cable is a single non-spring cable, the lifting of the printing platform will cause irregular accumulation of the cables, and the cables are easy to entangle and knot, causing the printing platform to move and jam. Or the cable is a single spring cable, the spring cable is heavy, the cable elasticity is too large, resulting in a heavy burden on the lifting of the printing platform, and the increase in the total length of the cable will lead to unstable signal transmission. Compared with the prior art, in the present application document, the cables connected to the functional electrical components include both spring cables and non-spring cables. The regular accumulation and extension of the spring cables can relieve the accumulation pressure of the cables, avoid entanglement and knotting caused by a large number of irregular accumulation of cables, and then avoid the influence of the cables on the lifting of the printing platform, while the non-spring cables avoid the redundancy of the cables caused by the use of all spring cables, avoid the heavy burden of the movement of the printing platform, and avoid the influence of the excessive length of the cables on the signal transmission.

[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation method, structure, characteristics and effects of the guide rail module proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] On the one hand, if Figure 1-4 As shown, the embodiment of the utility model provides a guide rail module for a three-dimensional forming device, and the guide rail module includes:

[0018] Slide rail 100;

[0019] The sliding assembly includes a sliding body 200 and a functional electrical component. The functional electrical component is arranged on the sliding body 200. The sliding body 200 is slidably connected to the slide rail 100.

[0020] The cable 300 is electrically connected to at least the functional electrical element. The cable 300 is used to transmit a detection signal of the functional electrical element. The cable 300 includes an elastic region 310 and a non-elastic region 320 .

[0021] In the present application, the slide rail 100 is used for the sliding body 200 of the sliding assembly to slide on the slide rail 100, playing a guiding role, and the slide rail 100 can also play a supporting role. The guide rail module in the present application can be applied to various types of printers, not limited to light-curing 3D printers. It can be used for any axis of a three-dimensional molding device.

[0022] The sliding assembly can slide on the slide rail 100. The sliding body 200 slides on the slide rail 100, and the functional electrical components are components on the sliding body 200 that need electricity, such as sensors, heating devices, etc.

[0023] In addition to the guide rail module, the three-dimensional molding equipment also includes a base and a printing platform.

[0024] In one embodiment, the slide rail 100 can be used to connect with the base, and can be detachably connected, or can be integrally formed. The first end of the sliding body 200 is slidably connected to the slide rail 100, the second end of the sliding body 200 extends away from the slide rail 100, and the second end of the sliding body 200 is suspended. The printing platform is connected to the second end of the sliding body 200, and the printing platform is used to be opposite to the light-transmitting area of ​​the base, or to be opposite to the material trough placed on the light-transmitting area. The guide rail module also includes a driver 800 and a transmission member, and the transmission member can be of various types, such as a conveyor belt, or a screw rod 600 and a nut 700 that cooperate with each other. Taking the cooperation of the screw rod 600 and the nut 700 as an example, the driver 800 is connected to the slide rail 100, the screw rod 600 is connected to the output shaft of the driver, the nut 700 is threadedly sleeved on the screw rod 600, and the sliding body 200 is fixed to the nut 700. The driver 800 is used to drive the lead screw 600 to rotate forward or reversely, and the driving nut 700 drives the sliding body 200 to rise and fall, thereby causing the printing platform to rise and fall relative to the material trough to achieve printing.

[0025] In one embodiment, the functional electrical element is used to be electrically connected to the main controller inside the base, and the functional electrical element can be used to detect the force of the sliding body 200, and generate a detection signal to send to the main controller, and then the main controller can judge whether the release is successful based on the detection signal. The functional electrical element can be a variety of components that can detect the force of the sliding body 200, such as a deformation sensor connected to the sliding body 200, and the deformation sensor can be set on the surface of the sliding body 200, or integrated inside the sliding body 200. During the printing process, the sliding body 200 will be deformed to varying degrees when it is subjected to force, and the deformation sensor is used to detect the deformation and generate a detection signal. Alternatively, the functional electrical element can be a tension gauge connected to the second end of the sliding body 200, and the printing platform can be connected to the tension gauge, and then a detection signal can be generated by detecting the tension or pressure of the printing platform.

[0026] The cable 300 is electrically connected to the functional electrical element, which can be a chip welding of the cable 300 and the functional electrical element. The cable 300 is also electrically connected to the main controller inside the base, which can be a chip welding of the cable 300 and the main controller to transmit the detection signal of the functional electrical element to the main controller. It can be approximately regarded as one end of the cable 300 is stationary, and the other end moves up and down with the sliding body 200. The cable 300 is spirally coiled and stacked in the elastic area 310, which can be stretched and retracted, and during the stretching and retracting process, the elastic area 310 maintains a spiral shape of different densities, which is a more regular shape. The cable 300 is a linear cable in the inelastic area 320. The cable 300 still has a certain degree of flexibility in the inelastic area 320, can be bent, and has no fixed shape, such as a partially approximately straight line shape, and another part is curved, or multiple areas may be curved to different degrees. The inelastic area 320 may present a variety of shapes according to the different positions of its two ends and the law of the change of the positions of the two ends, and will not be as regular as the elastic area 310. When the sliding body 200 drives the printing platform to rise, the elastic area 310 will stretch, and then increase the overall length of the cable 300 extending in the vertical direction to adapt to the movement of the sliding body 200. When the sliding body 200 drives the printing platform to descend, the elastic area 310 will shrink in a regular stacking manner, and the elastic area 310 will reduce the length of the cable 300 extending in the vertical direction, and then reduce the accumulation of the inelastic area 320, which can avoid the problem of knotting and entanglement caused by the large accumulation of the inelastic area 320. The elastic area 310 only occupies a part of the entire cable 300, so as to avoid excessive tension generated by the elastic area 310, especially when the sliding body 200 reaches a higher height, so as to avoid the wear of the transmission parts caused by the tension of the elastic area 310 pulling the sliding body 200. In addition, since the elastic region 310 is in the form of a coiled wire, this will increase the overall length and weight of the cable 300. By using the elastic region 310 which only occupies a portion of the entire cable 300, unstable signal transmission caused by the increase in length can be avoided, and the elastic region 310 being too heavy, which in turn increases the driving burden of the sliding body 200.

[0027] The utility model proposes a guide rail module and a three-dimensional molding device, which mainly realizes that the cables are not easy to pile up and knot by setting the cables connecting the functional electrical elements as a combination of spring cables and non-spring cables, and avoids damage caused by excessive cable tension, and avoids signal instability caused by excessive cable length. In the prior art, the cable between the induction element and the base of the 3D printer is a single-form cable. For example, if the cable is a single non-spring cable, the lifting of the printing platform will cause irregular accumulation of the cables, and the cables are easy to entangle and knot, causing the printing platform to move and jam. Or the cable is a single spring cable, the spring cable is heavy, the cable elasticity is too large, resulting in a heavy burden on the lifting of the printing platform, and the increase in the total length of the cable will lead to unstable signal transmission. Compared with the prior art, in the present application document, the cables connected between the functional electrical elements and the base include both spring cables and non-spring cables. The regular accumulation and extension of the spring cables can relieve the accumulation pressure of the cables, avoid entanglement and knotting caused by a large number of irregular accumulation of cables, and then avoid the influence of the cables on the lifting of the printing platform, while the non-spring cables avoid the redundancy of the cables caused by the use of all spring cables, avoid the heavy burden of the movement of the printing platform, and avoid the influence of the cable on the signal transmission due to the excessive length of the cable.

[0028] In one embodiment, in order to prevent the cable 300 from being pulled and causing the connection between the cable 300 and the functional electrical element to become loose, causing the cable 300 to become loose or affecting the transmission of the detection signal, the cable 300 is also fixedly connected to the sliding body 200, and the cable 300 is fixed in the area between the connection position with the sliding body 200 and the electrical connection position with the functional electrical element, or only moves slightly, to ensure the electrical connection strength between the cable 300 and the functional electrical element. The cable 300 and the sliding body 200 can be fixedly connected by plugging, clamping, or snapping. In order to prevent the cable 300 from being pulled and causing the connection between the cable 300 and the main controller to become loose, causing the cable 300 to become loose or affecting the transmission of the detection signal, the cable 300 is also connected to the slide rail 100. For example, the slide rail 100 includes a bottom end and a top end facing each other. When in use, the bottom end and the top end are arranged in the vertical direction, and the sliding body 200 moves between the bottom end and the top end of the slide rail 100. The slide rail 100 is connected to the base by the bottom end. Then the cable 300 can be fixedly connected to the bottom end of the slide rail 100, or it can also be fixedly connected to other positions of the slide rail 100, so that the area between the connection position of the cable 300 and the connection position with the main controller will not be extended or retracted by the movement of the sliding body 200. The fixed connection between the cable 300 and the slide rail 100 can be plug-in, clamping connection, snap-on connection, etc., or it can be fixedly connected to the electrical connection part on the slide rail 100. It is worth noting that the aforementioned cable 300 includes an elastic area 310 and an inelastic area 320. Specifically, the area between the connection position of the cable 300 with the slide rail 100 and the connection position with the sliding body 200 includes the elastic area 310 and the inelastic area 320, thereby achieving the aforementioned advantages.

[0029] The number and setting positions of the inelastic region 320 and the elastic region 310 can be various. The following takes the case where the cable 300 is fixedly connected to the slide rail 100 and the sliding body 200 at the same time as an example. In one embodiment, the first end of the inelastic region 320 is connected to the first end of the elastic region 310, the second end of the inelastic region 320 extends to the sliding assembly, and the second end of the elastic region 310 extends to the slide rail 100. The inelastic region 320 and the elastic region 310 are both single regions. The inelastic region 320 is adjacent to the sliding body 200, and the elastic region 310 is adjacent to the slide rail 100. The elastic region 310 can be supported by the slide rail 100, reducing the movement burden of the sliding body 200, and making the position of the elastic region 310 and the shape of the telescopic process more stable.

[0030] In another embodiment, the first end of the elastic region 310 is connected to the first end of the inelastic region 320, the second end of the elastic region 310 extends to the sliding assembly, and the second end of the inelastic region 320 extends to the slide rail 100. The inelastic region 320 and the elastic region 310 are both single regions, the elastic region 310 is adjacent to the sliding body 200, and the inelastic region 320 is adjacent to the slide rail 100, which can increase the degree of freedom of the connection position between the cable 300 and the sliding body 200, and avoid damage to the cable 300 caused by excessive bending at the connection.

[0031] In another embodiment, the number of the elastic region 310 and / or the inelastic region 320 is at least two, and the elastic region 310 and the inelastic region 320 are alternately arranged, for example, there may be two elastic regions 310, and the inelastic region 320 is located between the two elastic regions 310, and the two elastic regions 310 extend to the sliding assembly and the slide rail 100, respectively, so that many advantages of the aforementioned embodiment can be achieved. In addition, there are other combinations, which will not be listed one by one here.

[0032] In one embodiment, the bottom end of the slide rail 100 is used to connect to the base of the stereoscopic forming device, and the cable 300 is fixedly connected to the bottom end of the slide rail 100. On the one hand, it is convenient for the cable 300 to directly or indirectly connect to the main controller in the base; on the other hand, the elastic area 310 is extended and retracted in the vertical direction, and the cable 300 is connected to the bottom end of the slide rail 100, which can ensure that the shape of the elastic area 310 always remains in a relatively regular state. If one end of the elastic area 310 is set on the side wall of the slide rail 100, it may cause the middle part of the elastic area 310 to sink, etc., resulting in the problem of the elastic area 310 itself being knotted.

[0033] In one embodiment, a receiving cavity 101 and a clearance opening 102 are provided on the slide rail 100 , the clearance opening 102 is communicated with the receiving cavity 101 , the cable 300 is at least partially located in the receiving cavity 101 , and the cable 300 and the sliding assembly are connected through the clearance opening 102 .

[0034] The accommodating inner cavity 101 and the giving way opening 102 both extend in the moving direction of the sliding body 200. The accommodating inner cavity 101 accommodates at least part of the cable 300, which can prevent the cable 300 from being exposed and affecting the appearance, and prevent the cable 300 from being pulled on the sliding body 200 due to accidental contact or scratching. At the same time, the accommodating inner cavity 101 also limits the position of the cable 300, prevents the cable 300 from shaking, and prevents the cable 300 from expanding outward and causing unexpected deformation. If the elastic area 310 is arranged adjacent to the side wall of at least one side of the accommodating inner cavity 101, the accommodating inner cavity 101 can limit the extension direction of the elastic area 310 on at least one side. The giving way opening 102 is used to make way for the connection between the cable 300 and the sliding body 200. The giving way opening 102 can be arranged relative to the side where the printing platform is located, thereby making the structure more compact and the appearance simple.

[0035] The connection position of the cable 300 and the sliding assembly or the sliding body 200 can be located in the receiving cavity 101 or outside the receiving cavity 101. In one embodiment, the cable 300 extends out of the receiving cavity 101 through the clearance opening 102 to connect with the sliding assembly, and the clearance opening 102 can be slightly larger than the outer diameter of the cable 300. Alternatively, the sliding body 200 includes a suspension portion 210 and an extension portion 220, the suspension portion 210 is located outside the receiving cavity 101 and is slidably connected to the slide rail 100, one end of the extension portion 220 is connected to the suspension portion 210, and the other end of the extension portion 220 extends into the receiving cavity 101 through the clearance opening 102, and the cable 300 is connected to the extension portion 220 in the receiving cavity 101. By restricting the cable 300 in the receiving cavity 101, the risk of the cable 300 escaping from the clearance opening 102 can be reduced. Furthermore, since the extension part 220 has a fixed structural form, the cable 300 can be prevented from passing through the clearance opening 102 and extending outside the accommodating inner cavity 101, and the cable 300 is easily bent or collides with the clearance opening 102, causing a jam. The edge of the clearance opening 102 can be spaced apart from the extension part 220 by a certain gap, such as 0.5 mm to 1 mm, or the edge of the clearance opening 102 can be slidably abutted against the extension part 220 to guide the movement of the sliding body 200.

[0036] In one embodiment, when the slide rail 100 includes a bottom end and a top end facing each other, and the bottom end of the slide rail 100 is used to connect to the base of the three-dimensional forming equipment, the non-elastic area 320 extends from the connection position with the elastic area 310 to the top end of the slide rail 100, bends in a direction away from the top end of the slide rail 100, and extends in a direction away from the top end of the slide rail 100 to the side of the sliding component relative to the top end of the slide rail 100.

[0037] That is, the inelastic region 320 is connected with the sliding assembly or the sliding body 200, and the inelastic region 320 is approximately inverted U-shape. More specifically, the elastic region 310 and the inelastic region 320 are both single regions, and the inelastic region 320 includes a first vertical section 321, a curved section 322, and a second vertical section 323. One end of the elastic region 310 extends to the bottom end of the slide rail 100, and the other end of the elastic region 310 is connected with one end of the first vertical section 321. The other end of the first vertical section 321 extends upward and is connected with one end of the curved section 322. The other end of the curved section 322 is connected with one end of the second vertical section 323. The other end of the second vertical section 323 extends downward and is connected with the side of the sliding assembly relative to the top of the slide rail 100. The curved section 322 is an arc-shaped curve or an approximately semicircular curve, which is a curve toward the top of the slide rail 100. The lengths of the first vertical section 321 and the second vertical section 323 change in real time with the rise and fall of the sliding body 200, and the bending degree and length of the curved section 322 are also related to the rise and fall of the sliding body 200. For example, when the sliding body 200 rises, the curved section 322 will be pushed and change, the first vertical section 321 becomes longer, and the second vertical section 323 becomes shorter, while when the sliding body 200 descends, the first vertical section 321 becomes shorter, and the second vertical section 323 becomes longer. The inelastic region 320 is set in the above-mentioned curved form. On the one hand, the deformation of the inelastic region 320 can present a certain regularity, that is, the approximate regularity of the combination of the first vertical section 321, the curved section 322 and the second vertical section 323 is maintained, and the length change of the first vertical section 321 and the second vertical section 323 is used to adapt to the lifting and lowering of the sliding body 200, thereby avoiding irregular accumulation of the inelastic region 320; on the other hand, the inelastic region 320 is accumulated upward, which can make full use of the space of the accommodating inner cavity 101, or in other words, make use of the space of the accommodating inner cavity 101 above the sliding body 200.

[0038] In one embodiment, the layout direction of the first vertical section 321 and the second vertical section 323 is perpendicular to the extension direction of the sliding assembly. In other words, the plane where the inelastic region 320 is located is perpendicular to the extension direction of the sliding body 200, so that the movement trend from the first vertical section 321 to the second vertical section 323 is perpendicular to the extension direction of the sliding body 200, so that the first vertical section 321 to the second vertical section 323 is not easy to escape from the yielding opening 102, and the accommodating inner cavity 101 can be more fully utilized.

[0039] In one embodiment, the inelastic region 320 extends to the sliding assembly, the elastic region 310 is connected to the slide rail 100 , and the elastic region 310 and the sliding assembly are staggered at least in the moving direction of the sliding body 200 .

[0040] The elastic region 310 can give way to the sliding assembly, reducing the vertical space occupied by the slide rail 100. In the embodiment in which the slide rail 100 includes the accommodating inner cavity 101 and the giving way opening 102, the accommodating inner cavity 101 includes a first side wall and a second side wall opposite to each other, the giving way opening 102 is arranged adjacent to the first side wall of the accommodating inner cavity 101, the elastic region 310 is connected to the slide rail 100, and the elastic region 310 corresponds to the giving way opening 102 and the second side wall of the accommodating inner cavity 101. Figure 1 Taking the direction shown as an example, the clearance opening 102 is arranged corresponding to the rightmost side of the accommodating inner cavity 101, and the elastic area 310 is located on the left side of the accommodating inner cavity 101. Then, the elastic area 310 and the extension portion 220 of the sliding body 200 are staggered in the vertical direction, so that the descending height of the sliding body 200 is not restricted by the elastic area 310.

[0041] In one embodiment, the sliding assembly further includes a cable cover 400, the cable cover 400 is connected to the sliding body 200, the cable 300 at least abuts against the cable cover 400, and at least a part of the cable cover 400 is a flexible area.

[0042] The cable cover 400 is used to buffer and limit the deformation of the cable 300 at the connection position between the cable 300 and the sliding body 200, so as to avoid the cable 300 from bending significantly and to avoid the cable 300 from being damaged by bending. At the same time, in the embodiment in which the aforementioned non-elastic area 320 includes the first vertical section 321, the curved section 322 and the second vertical section 323, when the length of the sliding body 200 rising to the second vertical section 323 is very short and close to zero, the deformation of the cable cover 400 can play a supporting role for the curved section 322, and can reduce the curvature of the curved section 322, making the curved section 322 smoother, and avoiding damage caused by excessive bending of the curved section 322 or affecting signal transmission. The cable cover 400 can be flexible only at the edge, or can be made of flexible material as a whole, such as the cable cover 400 can be made of rubber or foam.

[0043] In one embodiment, the cable cover 400 covers a portion of the circumference of the cable 300, such as the cable cover 400 only covers a portion of the cable 300 relative to the first vertical section 321, which can prevent the bending section 322 from being excessively deformed as in the above embodiment. The cable cover 400 covers a portion of the circumference of the cable 300, and the cable cover 400 has no fixing effect on the cable 300, and the cable 300 can be fixed by other means. Alternatively, the cable cover 400 surrounds the cable 300. That is, the cable cover 400 is a cylindrical structure, and the axis of the cable cover 400 can extend in the vertical direction, or in other words, in the moving direction of the sliding body 200. The cable cover 400 can fix the cable 300 and prevent the bending section 322 from being excessively deformed as in the above embodiment.

[0044] In one embodiment, the connection method between the cable sleeve 400 and the sliding body 200 includes one of bonding, clamping, ultrasonic welding, and clamping connection. Alternatively, the cable sleeve 400 and the sliding body 200 are detachably connected, and when the cable sleeve 400 is deformed, aged, or broken after long-term use, the cable sleeve 400 can be easily replaced. Alternatively, the sliding assembly also includes a clamping portion 500, and the cable sleeve 400 is detachably clamped to the sliding body 200 through the clamping portion 500. The clamping portion 500 can realize the detachable connection of the cable sleeve 400, and the clamping portion 500 has a supporting effect on the cable sleeve 400. In particular, when the cable sleeve 400 is flexible as a whole, the clamping portion 500 can prevent the cable sleeve 400 from being pulled by the cable 300 and excessively bent. The clamping portion 500 and the sliding body 200 can be detachably connected, fixedly connected, or integrally formed.

[0045] On the other hand, an embodiment of the utility model further mentions a three-dimensional forming device, including any one of the guide rail modules mentioned above, and also including: a base and a main controller, the base including a containing inner cavity, and the main controller is located in the containing inner cavity.

[0046] The slide rail 100 is connected to the base, such as the slide rail 100 is connected to the base through the bottom end, which can be a bolt connection.
